dead users in utmp

[Max <davros@cyclone.Stanford.EDU>]

I have a strange problem with users not getting properly cleared out
of utmp when they kill the terminal instead of logging out.  Here's an
example.  Suppose a user logs in.  I type "who" and sure enough, he
shows up.  He then logs out by typing "exit", I type "who" and he's
gone.  But let's say he logs out by just killing his xterm.  I type
"who" and he's still in there.  However, he doesn't have any processes
running and doesn't appear when I type "w".  I would have thought the
utmp entry would have been cleared automatically, but for some reason
that's not happening.  If it matters, all of my users use tcsh and
this happens with both telnet and ssh logins.  Any clues?

Thanks,
    Max
