mtm 194cc11a54 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.
