v11i020: Idle demon

[Darren New]

It might be better to kill idle *programs* rather than idle *users*.
Any forground process running csh, rn, vi, .... could be killed
fairly harmlessly. Of course, the question of how to kill the csh which
invoked the rn which invoked the vi that somebody walked away from
is interesting. The best solution may be to patch the tty drivers
to report how long there have been outstanding read() calls, rather
than how long since something was typed.      -- Darren
