NUMA systems will trigger the new code - not just 'weird NUMA 
systems' - but i still think we could try the patches, the code looks 
straightforward and i booted them on NUMA systems and it all seems 
fine so far.

Anyway, i'll push the new sched/urgent branch out in a few minutes 
and then you'll see the full patches in the commit notifications.

Thanks,

	Ingo
