-/**
- * @class TAO_Resume_Handle
- *
- * @brief A utility class that helps in resuming handlers if TAO uses
- * a TP Reactor from ACE.
- *
- * Please read the documentation in the bugzilla #575 in the bugzilla
- * database what we mean by handler resumption.
- *
- * When TAO uses a TP reactor, it takes care of resuming the handler
- * once it makes sure that it has read the whole message out of the
- * socket. During the process of reading the transport object would
- * have to deal with errors in 'read' from the socket, or errors in
- * the messages that has been received. Instead of calling
- * resume_handler () on the reactor at every point in the code, we
- * use this utility class to take care of the resumption.
