   It is not possible to do this in general given the nature of CORBA
object references. (Try a dejanews search on Pacific Ocean Problem for
more information.) The client's reference count only affects the memory
taken up by the reference itself; it doesn't affect the server at all.
To destroy the server object you have to use the _boa()->dispose(obj)
call, which will destroy the object when its server-local reference
count hits zero. Clients may still have references afterwards, but they
will not be valid.
