I prefer java.util.concurrent.locks.Lock specify the behavior
of unlock() in this regard, instead of leaving it undefined.
implements Lock, and its 1.5.0 documentation does not seem
to say what the behavior of its unlock is. Ideally (for me)
I could just use a Lock reference and know unlock() will
check ownership for me, because the interface says it must.
