	No; while one process is waiting for the return value of it's method,
any incoming calls are processed - thus while we do not have threading,
we have re-enterancy which avoids this situation.

	It's worth noting that if you use bonobo you need to call
bonobo_activation before incoming CORBA method calls are processed
however.

	Regards,
