Folks, keep in mind why I asked this question in the first place.  My 
power supply was frying and I needed a VERY fast shutdown.  This was not 
asked as a fast way to shutdown just because we are impatient or 
something.  This was for the event of a serious emergency where I needed 
a shutdown in just a very few seconds not a minute or two.  Some of my 
services take a while to stop, foldingathome being the longest one.

Basically, this is not intended to be used to shutdown a puter on a 
regular basis, unless you burn out P/S's on a daily basis.  O-o

Just didn't want someone to be using this on a regular basis and then 
wondering why their system has a new nickname, FUBAR.  :'(
