No indeed, but you have problems with folks who periodically clean out
their /tmp directories, especially based on age of files... choice of two

Something else I was wondering. The problem was with a setuid version of
screen. I have:

    zsh, potato  2:04PM # ll `which screen`
    -rwxr-sr-x    1 root     utmp       216380 Sep  2 16:52 /usr/bin/screen*
    zsh, potato  2:04PM # 

The impossible question, someone tell me I'm an idiot: is there anything
exploitable through being setgid-utmp? :]
