Weird. Now I need to understand why. Thanks for stress testing
this. You have a ton of threads there.
I wonder if it is slow because of the large number of threads that
need stopping. I need to think about ways to avoid signalling threads
that are already on wait queues. I have a feeling this will require
changes to the Mutex implementation. Not too hard to do though.
