> I have a TNonblockingServer running with 1 worker thread and 10 IO thread.
> If there was a big task that just finished, all pending tasks might be
> expired. In such case, all IO threads are waiting for maxMonitor_, but the
> worker won't notify. It will remove all the tasks(all of them are expired)
> first. And then the notify code won't be executed because tasks are empty.
> Deadlock occurs.
> The patch move the if-notify statement out so it will notify even if all
> tasks are removed for expiration.
