your scheduler degraded the performance on my machine, rather than
boosting it. Half of that was the more complex stuff you added on
top ... it's a lot easier to start with something simple that works
and build on it, than fix something that's complex and doesn't work
well.
I still haven't been able to get your scheduler to boot for about
the last month without crashing the system. Andrew says he has it
booting somehow on 2.5.44-mm4, so I'll steal his kernel tommorow and
see how it looks. If the numbers look good for doing boring things
like kernel compile, SDET, etc, I'm happy.
