Yes, or at least non-trivial.  You can't have two processes listening on the
same port, so the server would have to stop listening and the daemon (who must
have been forked early in the boot sequence, like the name-lookup processes)
start listening before the checkpoint.  After the checkpoint, they'd have to
switch it back.  Complicated.
