Runnable -> Suspended -> Runnable, avoid 2 locks Allow some freedom in the Transtion code to change thread state without holding a lock in 2 cases where it is safe. 1) into Suspended we know that we're suspended and so checking the suspend count is a mute point. 2) when going into Runnable we can do a racy check before doing a secondary check after we've acquired a share on the mutator lock.
