An omniORB client opens a TCP connection to a server the first time an
operation invocation to that server process is made. After the call
returns, the connection is kept open for a while in case other calls
to the same address space are made. Subsequent calls use the existing
TCP connection. If no calls are made for a while, the connection is
closed.

If a client makes a call to a particular address space, and then
another thread on the same client tries to make another call to the
same address space, before the first one has returned, omniORB opens
another TCP connection.
