    This reminds me of a patch I did some time ago, without ever getting
    any feedback on it:

    http://lkml.org/lkml/2007/3/4/165

    In addition to just msleep, it converted all users of schedule_timeout()
    as well as sys_*select(). I actually ran with that patch on my
    main worstation for a few weeks, and while it did not crash, I
    saw some strange behaviour after all.
