- Add comments about the maintenance of the per-thread list of contested
  locks held by each thread.
- Fix a bug in the original BSD/OS code where a contested lock was not
  properly handed off from the old thread to the new thread when a
  contested lock with more than one blocked thread was transferred from
  one thread to another.
- Don't use an atomic operation to write the MTX_CONTESTED value to
  mtx_lock in the aforementioned special case.  The memory barriers and
  exclusion provided by sched_lock are sufficient.
