This contains fixes for a bug that could cause too much latency with non-zero
niced processes, as well as fixes so that it SMP balancing actually works now
(the v32 forward port on top of smpnice was buggy).

X should be reniced to -10 for best results.

/proc/sys/kernel/base_timeslice can be reduced if the default (large) timeslice
is causing interactivity problems.
