[cp-patches] FYI: CORBA performance fix: reuse the opened socket.

[Meskauskas Audrius]

Profiling shows that it is a real disaster to open/close a socket each time 
the remote method is called;
the duration of this operation can become a "bottleneck", limiting the 
performance of the whole application. I addition,
several thousands of the open/close steps may hit the bugs in the operating 
system or runtime environment.

The attached patch keeps the opened, but unused socket up till 7 seconds and 
has possibility to reuse it.
This behavior is much closer to the Suns CORBA client/server system than the 
previous strategy to
have a single socket per call. I have also implemented the supplementing 
feature to close the socket
explicitly, when required.

The changed version shows no regression in thetests we currently have.
