* @brief GIOP specific non-reactive message handler class
*
* This class does some of the message handling for GIOP. The class
* is non-reactive, in the sense that the read calls on the socket
* wait till all the data relevant for a GIOP message is read. This
* strategy can be used by protocols which uses the reactor for
* signaling rather than for data arrival.
*
* @todo Need to investigate why this strategy would be required at a
* higher level??
