I discovered that I was still running SCHED_ULE from yesterday and
switching back to SCHED_4BSD eliminated the problem.

I've actually been wondering why the system was so sluggish and now
I know why ;-)  Compiling a kernel was enough to drag the machine
practically to uselessness, but now it's back to it's old self.

The new scheduler still needs a bit of tweaking, methinks.
