Re: Specifying `blocking` and `timeout` when acquiring lock as a context manager

Here's another attempt at context managing:

@contextlib.contextmanager
def release_if_acquired(lock, blocking=True, timeout=-1):
     acquired = lock.acquire(blocking, timeout)
     if acquired:
         yield acquired
         lock.release()
     else:
         yield acquired

I should not have used a temporary.

@contextlib.contextmanager
def release_if_acquired(lock, blocking=True, timeout=-1):
     if lock.acquire(blocking, timeout)
         yield True
         lock.release()
     else:
         yield False
