key to identify a wait bit queue or NULL
Sets current thread back to running state and removes the wait descriptor from the given waitqueue if still queued.
Wakes up the next waiter if the caller is concurrently woken up through the queue.
This prevents waiter starvation where an exclusive waiter aborts and is woken up concurrently and no one wakes up the next waiter.
