Ahh, you're right.  I don't know why I was thinking it was part of an
init script on boot or something..

I would think, if you have more than one machine, and APM on it,=20
apm -s

then work on another machine, write the scripts to kill everything, then
just copy your script to the machine after you wake it up..?

Or if it's not being run by root, but by someone else, you could killall
the process' from that group?  Not sure if or how you can do this..
killall -g group-name  ??
