I've tracked down the message to the CORBA_ORB_Shutdwn:
	

void CORBA_ORB_shutdown (CORBA_ORB           orb,
		    const CORBA_boolean wait_for_completion,
		    CORBA_Environment  *ev)
{
	PortableServer_POA root_poa;

	root_poa = g_ptr_array_index (orb->adaptors, 0);
	if (root_poa) {
		PortableServer_POA_destroy (
			root_poa, TRUE, wait_for_completion, ev);
		if (ev->_major) {
			if (wait_for_completion)
				g_warning ("FIXME: wait for "
					   "completion unimplemented");
			else
				return;
		}
	}

	giop_shutdown ();

	ORBit_ORB_shutdown_servers (orb);
}

Is this the flag you were referring previously? Is there a way to
flush the data?

All I can say is :-O !

Given the fact that a patch on Orbit does not look probable, what
would your advice on the issue be? Just use the sleep workaround or
could there be a better way?

 I've actually thought of running bonobo_main in an atexit function
and then running bonobo_quit_main in a g_idle function. If this
manages to avoid the message  I would try to hook this in the ruby
interpreter and see if it doesn't explode.
