You can have S rebind to the same port/object key each time.  See omninames
for an example of how to do this.  If this isn't acceptable, I think you
will have to catch COMM_FAILURE exceptions and rebind.  It sure would be
nice to have a virtual function _rebind() that you could override to rebind
to the server object in case COMM_FAILURE is thrown.  I suppose you could
add this kind of feature since you have the source.
