Enormous utmp since mpsafetty

Has anyone else noticed that /var/run/utmp sometimes grows to insane sizes
(998M) since mpsafetty?  I've been trying to pinpoint the culprit but I
haven't been successful so far.

I don't think mpsafetty itself is to blame.  Rather something which expects
our old tty system.

My original reaction was to blame screen, but I can't immediately see where it
might be going wrong.

Mysterious.  Anyone have any ideas?
