There is little help we get from userspace, and i'm not sure we want to add scheduler overhead for this single benchmark - when something like a _tiny_ bit of NUMAlib use within the OpenMP library would probably solve things equally well!
There's has been a general problem with sched domains and it trying to meet two goals: "1) spread things around evenly within a domain and balance across domains infrequently", and "2) load up cores before loading up siblings, even at the expense of violating 1)". We've had trouble getting both 1) and 2) implemented correctly in the past. If this patch gets us closer to that nirvana, it will be valuable regardless of the benchmark it also happens to be improving. Regardless, I agree it will need good testing, and we may need to pick the wheat from the chaff.
