Retesting today with 2.6.21-rc3-git7 + 2.6.21-rc3-sched-rsdl-0.30.patch.

Still not pleasant to use the GUI with a kernel build (-j1 or -j2) happening

Also, accounting looks weird in top(1).
With a 100% busy machine, top will show something like this :

Mmm.. I wonder where all of that 100% CPU went to.. the busiest tasks
are only showing up as 4.0% and 1.7% (when in fact they are using near 100%).
