Sounds like a reasonable explanation. Screen works without the
setuid bit, and with /tmp/screens mode 1777. I noticed that my login
sessions in screen don't show up in a who or a finger. I seem to
recall an option (either compile- or run-time) that controls this
login behaviour, but I need to look at the source again... it's been a
while since I've used screen.
