    These 3 points are definately true.

    I'm not sure about this... I am sure that we won't be able
    to measure the difference however ;)
    My doubt is mainly between improvement and no improvement.
    Like Richard, I'm quite sure that there won't be any loss.

    These points are valid too. In the current scheduler code,
    a process meets 3 separate tests if(p->policy != SCHED_OTHER),
    it sure would be nice to separate the paths and make the
    asm a little bit more straightforward (and faster).
