But its not true.  As Andrew has already pointed out, callbacks are not
broken on server shutdown.  In any case, callbacks have a life span of
minutes to hours.  Even if a callback was recorded that was a week old,
it would not trigger an RPC to the client when it came time to break
callbacks on the associated object.
