    SubjectRe: [PATCH] Minor scheduler fix to get rid of skipping in xmms
    Ok, looks like I reversed 2 set of results yesterday when I posted.  
    Here is a more complete (and hopefully accurate) reporting of the 3 patches.

    A) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch
    degrades volanomark, specjbb and specsdet

    B) *** test5 + sched-balance-fix-2.6.0-test3-mm3-A0.patch
    improves specjbb with no real change on sdet or volanomark

    C) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch + sched-balance-fix-2.6.0-test3-mm3-A0.patch
    degrades volanomark and sdet, more degrade than improvement on specjbb

    D) *** test5 + sched-CAN_MIGRATE_TASK-fix.patch + sched-balance-fix-2.6.0-test3-mm3-A0.patch + sched-2.6.0-test2-mm2-A3.patch
    degrades volanomark and sdet, mixed results on specjbb



    Below are the details for each of the runs.
