	Nope; you need to do either a CORBA_ORB_run in 1 thread, or run a
g_main loop elsewhere.

	Can you show me a stack trace for this; I just can't see how that could
happen. OTOH, I've added some extra locking to the main thread unref
case, since [ I suppose ] we're not certain it's the last unref anymore
by the time we do the g_object_unref in the worker thread, so we have to
check again :-)
