All other times it does Sleep(0). I'll give it a go, but I've noticed that the yield() implementation is tricky to get right. I guess it depends a lot on how often yield() is called from the rest of Rockbox. > I've also added a Sleep() in sleep(). But there was already a sleep in sleep, so I don't see the point. (Your patch does make there's always a "real" sleep, even if HZ should ever be > 1000...)
