Hi,
Patch against 2.6.0-test4. It fixes a lot of problems here vs
previous versions. There aren't really any open issues for me, so
testers would be welcome.

The big change is more dynamic timeslices, which allows "interactive"
tasks to get very small timeslices while more compute intensive loads
can be given bigger timeslices than usual. This works properly with
nice (niced processes will tend to get bigger timeslices).

I think I have cured test-starve too.

Worst case scheduling latency for a very nice (19) process I have
observed is about 210ms during a niced make -j3 and frantic window
moving in X, on a UP... I did see one of Con's recent kernels have a
worst case of >7s.

On the other hand, I expect the best cases and maybe most usual cases
would be better on Con's... and Con might have since done some work
in the latency area.
