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.
