If the object really is deactivated, id_to_reference will throw
ObjectNotActive. However, there is no guarantee that deactivation has
completed when deactivate_object returns, since deactivation is often
done by a separate thread.

The best way to know when the last request on an object has finished,
and it has been successfully deactivated is to use a POA with a
ServantActivator. That way, the etherealize method will be called when
the object is deactivated.

Cheers,

Duncan.
