  Log:
  o The mutex locking functions aren't normally cancellation points. But,
    we still have to DTRT when an asynchronously cancellable thread is
    cancelled while waiting for a mutex.
  o While dequeueing a waiting mutex don't skip a thread if it has
    a cancel pending. Only skip it if it is also async cancellable.
