I assume that this new scheduler is only for SMP?

I tried it out on my UP machine - BTW on line 312 there's a missing
``);'' - and the results were, not to pull any blows, catastrophic.

Running X I started a ``make buildworld'' in an aterm and immediately
observerd:
o the cursor lagged way behind mouse movements
o switching desktops allowed me to observe in detail how various
  applications repaint themselves - it was that slow
o mozilla was totally unusable

With the current scheduler interactive applications are still quite
snappy. I never observe any of the above mentioned problems with it.
I know this is a WIP, but I thought I'd report my observations.

This on an XP 1800+ with 768MB of memory and (fairly) fast SCSI disks.
