UISIMULATOR: Give the host OS some needed context switching hints (which _is_ supposed to work on Linux - but I can't tell on VMWare - and does on Windows). I guess I'll know for sure soon. Give sleep() even more genuine behavior. Add some button driver sync with the rockbox threads that should have been there for some time - this is basically interrupt-like processing as any thread not in the kernel pool should be considered. Make the screendump work again by posting the request. Perhaps help out shutting down for some users but not in the way I'd prefer - to think about.
