I have seen this same behavior, on both an SGI and a SUN; so I would guess
this isn't a platform-specific bug.  Hats off to Peter for providing
such a concise description; I never had the patience to actually
figure out what I had done to make this happen, and then to write up a
bug report.

And yes the bell ringing stuff is pretty hideous.  Our worstations are
in a common room, so when epoch loses it's marbles, everyone knows
about it.  The best thing to do is to login from somewhere else and
kill epoch; but there might still be 32K bells left in the buffer
waiting to be echoed.
