	Hmm..  I might be NetBSD's odd (that desciptor has a small scope :^) 
locations of utmp, wtmp and lastlog, or the owner/modes of those files or screen.
I had a vaguely similar problem in that xterm didn't make entries in these files.
I solved it for xterm by recompiling with NetBSD's locations (as defined in 
<utmp.h>).

	Sounds like it's not removing the entry from utmp.  Might want to check 
out why it would make but not remove an entry.  What happens when you try to 
'write' to an almost logged out user's tty? Be interesting to see how it handles 
that... error message? complete confusion?

	Incidentally, the xterm I recompiled is available for ftp from 
eth217.hampshire.edu:/pub/NetBSD/Local.
