I was reading an interview last night (found from /.) on the O(1) scheduler. One thing that was mentioned was batch
taskswhich get only cpu that's not being used for other things, in blocks of 3 seconds. It has some harder enforcement
ofnice levels (i.e. batch @ 10 can completely prevent a batch @ 15 from running untill it completes, but is completely
interruptableby ordinary processes). Since all the parameters are tweakable, many while running, this may be a place
tolook.
