  Log Message:
  -----------
  Use pthread mutexes directly when NDEBUG.
We only need the extra state for debugging and invariants.  This
greatly reduces overhead, and doubles the throughput of
callback-speed1.

  Log Message:
  -----------
  Track whether a Callback has been descheduled.
This allows us to avoid acquiring the scheduler's lock when cancelling
the Action associated with a Callback which is being executed while it
has been descheduled.
With NDEBUG, this yields a ~30% improvement in callback-speed1.
