Rafael, we can close this bug i think. The group scheduler related 
interactivity problems in early .25-rc were resolved via:

| commit 62fb185130e4d420f71a30ff59d8b16b74ef5d2b
| Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
| Date:   Mon Feb 25 17:34:02 2008 +0100
|
|     sched: revert load_balance_monitor() changes
[...]
|    Namely:
|     - very frequent wakeups on SMP, reported by PowerTop users.
|     - cacheline trashing on (large) SMP
|     - some latencies larger than 500ms

that includes Xorg's fragility to certain types of delays. It should be 
resolved by now and i havent seen it resurface.

we are now back to the 2.6.24 state of things. Which isnt as perfectly 
interactive as the non-group-scheduler 2.6.24, but which is still more 
interactive than say 2.6.22.

Peter is working on improving it even more, but that's 2.6.26 material.

	Ingo
