optimize away these loops. Change boolean to int to match what atomic API supplies. Remove wmb() since the atomic_store_rel() on status.done ensure the prior writes to status. It also fixes the fact that there wasn't a rmb() before reading done. This should also be more efficient since wmb() is fairly heavy weight.
