Haven't gotten to that.  I started building a kernel without DEBUG, and
sure enough, Mozilla became unusable.

So I reniced Mozilla and X to -20, and it became usable again.  I am now
leaning towards scheduling.

Hmm.  I have HZ defined to 1000; I wonder if that's a component of this, it
might mean that I'm losing time to context switches when the system is loaded.
