As I said in my original email, _non_existent is the standard method.
_remote_non_existent is an omniORB implementation detail. It may be
changed or removed in a future version.

If an object does not exist, _non_existent returns true;
_remote_non_existent throws CORBA::OBJECT_NOT_EXIST.

I can't think of a situation off-hand where _non_existent will return
false, but it might happen with some pseudo object references like
CORBA::Policy. Or it could happen with a normal object reference that is
used after it is released if you were unlucky about memory reuse.
