	The problem here is that we are finalizing the servant as it
is exectuing a request. If you read 11.3.8.17, you'll see that the
poa is not supposed to complete the object's deactivation until all
requests are completed.

	The correct fix is not to call finalize at all, but let the
POA call it, which it does.

	Okay, so etherealialization is breaking the bond between
servant and object. This is not supposed to happen until the object
has been deactivated.

	Yes, this would break the spec.

	So the moral of the story is - remove the call to finalize.
The POA will do it.

Good Luck,
Mark.
