In Synch_Twoway_Invocation::remote_twoway I found some strange code. We do retrieve the cdr stream with:

TAO_OutputCDR &cdr = this->resolver_.transport ()->out_stream ();

this then goes to the transport, then to the messaging object (which is GIOP_Message_Base) and then retrieves there the out_stream. A few lines further we do write the header and pass the stream. This then ends up again in GIOP_Message_Base. Why do we pass the stream through the chain when we marshal the header?

Also, why doesn't the GIOP_Message_Base expose its stream. If it would keep it private we don't have to check which parser to use each time. At the moment we get an init, or parse an incoming stream, we set the correct parser as member pointer and then don't have to worry again until we get a new init of a new parser.
