The CATS programmers on campus once installed an idle-user killer
on our open-access system, to free up ports on a heavily loaded
IS68K running 4.2BSD. It would sit in background waiting for your
tty to be silent for say, 15 minutes, before logging you out.
Needless to say, students didn't appreciate this 'feature', as
logging back in entails waiting on a 10 minute queue. So people
ran 'yes' and left their terminals for hours on end logged in.
So far, the programmers haven't caught on :)
