This is pretty much the same problem I had after getting logins to work
under NeXT.  I could not see a clean way of doing it besides tracking the
orignal ttyslot() output until it was needed to clear the utmp file.  I
ended up just tracking what tty the user was on and wrote a primative
ttyslot(char *) that took in the tty and returned the slot to change.

That patch should help NeXT (I did something like that before, but it
was not as clean nor was finished) resolve it's utmp/wtmp issues.
