[omniORB] local invocations

[Carl Thompson]

You don't have to go through the marshalling and unmarshalling if the 
_process_ is the same (if implementation object and proxy object are in the 
same program).  In this special case I think omniORB short circuits the 
marshalling and unmarshalling.  But if you are talking about two separate 
processes, you must still do it.  (I'm not an expert on ORB internals, so 
someone please correct me if I am wrong.)

But I think omniORB4 allows you to use Unix domain sockets if the processes 
are on the same machine which may speed things up quite a bit.
