If I want to acquire a `threading.Lock` using the context manager

is it possible to specify the `blocking` and `timeout` arguments that
`acquire` would usually take?
Not that I know of, but why would you want to? There's no built-in 'if'
with a 'with' block -- how would your code know whether it ran or not?
Perhaps defer release, a la a common Go pattern:
with contextlib.ExitStack() as stack:
acquired = lock.acquire(blocking=False)
if acquired:
stack.callback(lock.release)
