Just to clarify what Andreas is saying: I was forced to rename my SCHED_BATCH 
to SCHED_IDLEPRIO which is a more descriptive name anyway. That is in my 
2.6.16-rc based patches. SCHED_BATCH as you know is now used to mean "don't 
treat me as interactive" so I'm using this policy naming in 2.6.16- based 
patches.

Cheers,
