[omniORB] Patch for omniORB 4.0.3

[Serguei Kolos]

Hello

The problem:
Server is running in thread pool model.
A request arrives to the server and is started to be processed. If at 
that moment
the server calls ORB::shutdown before the request processing has been 
finished then
the server hangs in the giopServer::deactivate() (line 527: 
pd_cond.wait();). This happens
because the worker for that connection calls 
notifyWkDone(this,exit_on_error) with exit_on_error=0
(giopWorker.cc line 218) since the request has been processed 
successfully, but then
nobody notice that this connection has been shutdown.

The patch, which solves the problem is attached at the end. I'm not sure 
that this is the best solution,
but it works.
Cheers,
Sergei
