I've not seen John's problem before, so I can't comment on that. However,
it is not the problem related by Goetz (which is patched and fixed as he
related). In that situation, one had a true three-way deadlock. Putting
a printer online (or any other event) would not relieve the impasse; it
was truly necessary to reboot the system.
