    SubjectRe: [PATCH] 2.6.3-rc3-mm1: sched-group-power
    Nick, I'm not sure what capability this patch adds .. perhaps some words
    of explanation.

    So we have SMT/HT situations where we'd prefer to balance across cores;
    that is, if 0, 1, 2, and 3 share a core and 4, 5, 6, and 7 share a core,
    you'd like two processes to arrange themselves so one is on [0123] and
    another is on [4567]. This is what the SD_IDLE flag indicated before.

    With this patch, we can "weight" the load imposed by certain cpus, right?
    What advantage does this give us? On a given machine, won't the "weight"
    of any one set of SMT siblings and cores be uniform with respect to all
    the cores and siblings anyway?
