That would certainly work, but in my case there are some users, power users if you will, 
that I don't want to kick off.  A bunch of the IDs on my system are shared, almost 
kiosk-like, and those are the ones I want to reset.  Plus, I like the idea of killing 
only those IDs I explicity specify, to avoid any unforeseen consequences.  If I had 
hundreds of these IDs that needed to be pkilled, I might feel different; but even then, 
I think I'd just spend a bit of time refining the list of those IDs and stick with the 
'kill only those I say' approach.
