    Hi Kurt,
    I'm sorry I can't comment too much on your patch, as I am not
    too familiar with 2.6's scheduler policy. Never hurts to have
    another pair of eyes looking at it though.

    Does it help any actual interactivity problem? Unfortunately
    practically any you make to the scheduler is bound to make
    things worse for at least one person, so it is difficult to
    just test things out.

    Maybe we could include a compile (or even boot) time selectable
    schedulers to test improvements. Or wait for 2.7 and backport
    good bits. These two options still have the problem that most
    of the users that matter still won't test them...

    That said, if you have any real, reproducable problems that it
    solves, you far improve your chances of it being picked up (in
    one form or another).

    Nick
