+ *
+ * Please read the documentation in the TAO_Transport class to find
+ * out more about the design of the outgoing data path.
+ *
+ * In some configurations TAO needs to maintain a per-connection queue
+ * of outgoing messages.  This queue is drained by the pluggable
+ * protocols framework, normally under control of the ACE_Reactor, but
+ * other configurations are conceivable.  The elements in the queue
+ * may may removed early, for example, because the application can
+ * specify timeouts for each message, or because the underlying
+ * connection is broken.
+ *
+ * In many cases the message corresponds to some application request,
+ * the application may be blocked waiting for the request to be sent,
+ * even more importantlyl, the ORB can be configured to use the
+ * Leader/Followers strategy, in which case one of the waiting threads
+ * can be required to wake up before its message completes
+ * each message may contain a 'Sent_Notifier'
+ *
+ * <H4>NOTE:</H4> The contents of the ACE_Message_Block may have been
+ * allocated from TSS storage, in that case we cannot steal them.
+ * However, we do not need to perform a deep copy all the time, for
+ * example, in a twoway request the sending thread blocks until the
+ * data goes out.  The queued message can borrow the memory as it will
+ * be deallocated by the sending thread when it finishes.
+ * Oneways and asynchronous calls are another story.
+ *
+ * @todo: Change the ORB to allocate oneway and AMI buffer from global
+ *        memory, to avoid the data copy in this path.  What happens
+ *        if the there is no queueing?  Can we check that before
+ *        allocating the memory?
