on some systems, you have the option to kill all ancestors of a
process by putting a - in front of the process number. This has the
nice effect that a 'kill -9 -1' (all descendants of init (which inherits
all lost processes and is also the indirect parent of all your
processes)). This has the effect of trying to kill almost every process on
the system (yes, don't do this if you are root!), the end result being
that all of your processes are killed, and no-one else is effected due
to permissions restrictions.

This doesn't work on all systems but from memory it works on hp-ux (HP),
umax (encore), dynix (sequent), and whatever the pyramid OS is called.
I don't think it works on sun's (but I am quite likely to be wrong on
this).
