``oneway'' keyword and the deferred synchronous operations
(send/get_response) only guarantee that the operation is performed at most
once and the requester never synchs (hence async) with the completion.
what this means is that a orb could simply discard the invocation message
and still be compliant.  in addition, the specs don't enforce request
calls to be non-blocking.  for example, the client could still block an
entire process on a oneway call just because the network is congested
(filled buffers) or the server busy.  maybe gnome needs a little firmer
definition of what's an asynch object requests than this.
