Nowhere does the documentation say this. You can't call -[NSLock
lock] multiple times, because you'll block on a lock you already have
(that's why we have recursive locks). Otherwise -[NSLock tryLock]
would be quite useless, wouldn't it?

implement a spinlock on top of NSLock. Don't do this. Just use
@synchronized.
