I'll add another comment at the right place. Additionally, I don't get this `check-wait(timeout)-check-wait(timeout)-...` logic. It doesn't make sense to me, there's no additional fail-safe logic inside the loop, why don't just `wait()`? Instead, it releases the lock in every second probably without any benefit. I don't say we have to change that, I just don't understand. -- This is an automated message from the Apache Git Service.
