OK, good point.

If you'd like, you could replace your "pending" lists with
collections.deque which is supposed to be suited better to your use
case, especially for the .pop(0).
I'd expect the scanning to be IO-bound in most cases, so keeping the
lists should be acceptable (if you don't want to retest with the deque).
