Yanking the power cord works with nearly all past and present machines.
If you are patient and willing to wait for some machines internal UPS
(our AT&T 3B20 has biga** truck batteries in the back) to run down, the
percentage goes up. Of course it isn't really the best way, but it
works. I have no problems with it because any computational nodes that
get irrepairable software type problems from such an approach just get
reinstalled with "Dean's Magic Disk" (read "aint kickstart great"). ;-)
