UISIMULATOR: Trying to make it snappy for everyone. Remove forced thread yield in switch_thread which starves threads that call it alot especially on fast 64-bit machines (which could yield _alot_ of time away). I suspect that was a way to get I/O to run better before having an I/O thread...and it did help before that addition. No longer needed it seems and the OS seems to handle scheduling without hints just fine.
