Results from reaim aren't encouraging.
patch was applied against 2.6.0-test8 - the result
is PLM #2232

The kernel doesn't perform well at larger user numbers.
Notice the different in max users.
Compare the graphs for jobs per minute, the usual graph
is quite flat, see:
http://khack.osdl.org/stp/281932/results/jpm.png
With the v16 scheduler, jobs per minute falls off rapidly
as user number increases giving graph with a steep slope,
not good.
