-	This set of changes comes with complete revamping of the previous
-	design. The flaws with the previous design were as follows
-	(1) We were unnecessarily penalising large data blocks. We were
-	    trying to read a particular size of data till the data was
-	    completely removed from the socket. This was totally
-	    ridiculous because we were doing more reads than required.
-
-	(2) The message block that was constructed on the stack with a
-	    buffer from stack never did what we wanted. It was allocating
-	    a data block on the heap and was thus spoiling whatever
-	    optimization that we had tried putting in.
-
-	(3) The incoming message Queue is now managed by the TAO_Transport
-	    object instead of the GIOP classes.
-
-	* tao/GIOP_Message_Base.cpp:
-	* tao/GIOP_Message_Base.h: Removed the references to the incoming
-	  message queue. Implemention for two methods missing_data () and
-	  byte_order (). Added an extra argument to the methods
-	  process_request_message () and process_reply_message (). Used
-	  the incoming message block to create a input CDR with the
-	  DONT_DELETE flag so that the data block is not deleted after
-	  request processing.
-
-	* tao/GIOP_Message_State.cpp: Removed the inclusion of
-	  Transport.h.
-
-	* tao/Incoming_Message_Queue.h:
-	* tao/Incoming_Message_Queue.cpp:
-	* tao/Incoming_Message_Queue.inl: Added an argument to the
-	  add_message (). Further the implementation of add_message () has
-	  changed a bit. It now adds only a new message to the queue. It
-	  doesn't modify a half filled queue. The TAO_Transport object
-	  does that job. So declared the TAO_Transport as the friend class
-	  of the Incoming_Message_Queue.
-
-	  Changed the name of the methods complete_message () as
-	  is_complete_message (). Removed the methods current_message ()&
-	  current_byte_order ().
-
-	  Added a new method copy_message () which copies messages into
-	  the half empty nodes.
-
-	  Added a method wr_ptr () to access the write pointer of the tail
-	  node that has halfempty message.
-
-	* tao/Transport.cpp:
-	* tao/Transport.h: The Incoming Message Queue is now managed by
-	  this class. Added the following methods
-	  - missing_data ()
-	  - parse_incoming_messages ()
-	  - check_message_integrity ()
-	  - consolidate_message ()
-	  - conslodate_message_queue ()
-
-	* tao/Pluggable_Messaging.h: Added two new virtual functions
-	  missing_data () and byte_order ().
-
-	* tao/ORB_Core.h:
-	* tao/ORB_Core.cpp:
-	* tao/ORB_Core.i: Added an accessor for the locking_strategy used
-	  for the CDR blocks.
-
-	* tao/Synch_Reply_Dispatcher.cpp:
-	* tao/Asynch_Reply_Dispatcher.cpp:
-	* tao/DynamicInterface/DII_Reply_Dispatcher.cpp: Changed the
-	  exchange_data_block () to clone_from () which is a new method in
-	  ACE_InputCDR.
-
-	* tao/LIST_OF_TODO: Updated the list

-
-	* tao/Incoming_Message_Queue.cpp:
-	* tao/Incoming_Message_Queue.inl: Fixed a bad way to use the tail
-	  of the circular linked list. This is now replaced by the size of
-	  the linked list. This fixes quite a few errors.
-
-	* tao/Transport.cpp: On read () if we get errno === EWOULDBLOCK we
-	  were closing the connection prematurely. This is not right. We
-	  should only return a 0 to the reactor, so that it can call us
-	  back when there is data in the socket.

-
-	* tao/GIOP_Message_Base.cpp (process_reply_message): Fixed the
-	  reply parsing and generation of the CDR stream that is passed on
-	  to the higher layers of the ORB.

-
-	* tao/GIOP_Message_State.h:
-	* tao/GIOP_Message_State.inl: The message_size () now returns the
-	  payload size + the GIOP header length. Added a new method
-	  payload_size () that returns the payload size alone.
-
-	* tao/GIOP_Message_Base.cpp: Fixed a warning with g++ builds.
-
-	* tao/Connection_Handler.h:
-	* tao/Connection_Handler.cpp: The svc_i () method now calls
-	  handle_input_i () on the transport instead of the method in the
-	  same class. The handle_input_i () in the TAO_Connection_Handler
-	  class has been removed as it is no longer used.
-
-	* tao/IIOP_Connection_Handler.h:
-	* tao/IIOP_Connection_Handler.cpp: Removed the implementation of
-	  handle_input_i ().
-
-	* tao/Incoming_Message_Queue.cpp: When trying to make a new data
-	  block we dont add the size of GIOP header. The message_size ()
-	  now returns with that value.
-
-	* tao/Incoming_Message_Queue.inl: Fixed a link error in g++
-	  builds.

-
-	First set of checkins for big two ways.
-
-	* tao/Connection_Handler.h: Added #define for the default
-	  buffer size . Not sure yet whether this is the right place for
-	  it.
-
-	* tao/Incoming_Message_Queue.h:
-	* tao/Incoming_Message_Queue.cpp:
-	* tao/Incoming_Message_Queue.inl: Queue up the incoming
-	  messages. We form a circular linked list of messages that are
-	  bigger than a particular buffer size. During processing we take
-	  messages of the queue to pass it onto the higher layers of the
-	  ORB.
-
-	* tao/GIOP_Message_Base.cpp:
-	* tao/GIOP_Message_Base.h: Added support for big two way
-	  requests. If the message has only been partially read we add the
-	  message in the queue and then go for the next read. During
-	  processing we check if the queue has messages before processing
-	  the message on hand.
-
-	* tao/GIOP_Message_State.h:
-	* tao/GIOP_Message_State.cpp:
-	* tao/GIOP_Message_State.inl: Added accessor methods.
-
-	* tao/Transport.cpp: Added support for bigger two ways. If we
-	  receive a two way bigger than a particular size we read and
-	  queue the message and do a further read to retrieve the rest of
-	  the message.
-
-	* tao/TAO.dsp: Added new files.
-	* tao/default_resource.cpp: For single threaded configuration we
-	  have been creating a locked data block and that seems to defy
-	  logic. We now should create a lock free datablock for single
-	  threaded configurations.

-
-	* tao/* : Merged with the main trunk.
-
-Fri Jun  1 17:22:29 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
-
-	* tao/GIOP_Message_State.cpp (parse_message_header_i):
-	* tao/Connection_Handler.cpp:
-	* tao/GIOP_Message_Base.cpp:
-	* tao/Makefile:
-	* tao/Transport.cpp: Fixed warnings and errors in Linux g++.
-
-Thu Jun 01 13:39:02 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
-
-	* tao/Transport.cpp:
-	* tao/Transport.h:  Added the following methods -- handle_input_i
-	  (), process_parsed_message (). The handle_input_i () creates a
-	  buffer on the stack. It uses the buffer to read the
-	  messages. Any errors in read () or dealt here directly. The read
-	  message is then parsed and processed by the GIOP classes. Moved
-	  most of the code for processing here as they seem to be common
-	  between different transport protocols. Once we have received a
-	  full message, we just resume the handler and go ahead with
-	  processing the message.
-
-	* tao/IIOP_Connection_Handler.cpp (handle_input ()): Calls
-	  handle_input_i () on the transport.
-
-	* tao/Connection_Handler.h:
-	* tao/Connection_Handler.cpp:  The svc_i () calls the
-	  handle_input_i () on the transport instead of the same call on
-	  the connection handler. This way we should be able to share the
-	  same code among different protocol objects.
-
-	* tao/GIOP_Message_State.h:
-	* tao/GIOP_Message_State.cpp: Much of the message parsing and
-	  state information is stored here.
-
-	* tao/GIOP_Message_Base.h:
-	* tao/GIOP_Message_Base.cpp:
-	* tao/Pluggable_Messaging.h: made some changes to suit the
-	  above. But more changes could come in, to suit different
-	  protocols. We may want to change the interfaces in
-	  Pluggable_Messaging to give a much cleaner interface to the
-	  world.
-
-	* tao/Wait_On_Read.cpp: Used the handle_input_i () on the
-	  transport for processing the incoming data.
-
-	* tao/TAO.dsp:
-	* tao/PortableServer/TAO_PortableServer.dsp: Added new files and
-	  removed files from GIOP_Lite in the first round.
-
-	* tao/GIOP_Message_Reactive_Handler.cpp:
-	* tao/GIOP_Message_Reactive_Handler.h: Looks like these files
-	  would be removed during the final merge.
-
-	The above checkins works for simple two way calls. The
-	BiDirectional_NestedUpcall test works with the TP_Reactor. This
-	works on Win32.
-
-
-Thu May 24 12:19:02 2001  Balachandran Natarajan  <bala@cs.wustl.edu>
-
-	* tao/Transport.h: Added some design forces for the input data
-	  path.
