Now I'm trying to figure it out by set a short channel timeout.
Work flow is basically like this:
1. Start a new thread to set the channel timeout to one second or so.
2. buffer = channel. recv(256) output += buffer in a while True: loop,
break if timeout occurs.
3. In the main thread, make the new thread join(0.5) if isAlive()
4. If it's NOT alive, process the output as you want.
It may add additional 1-2s' delay, But it doesn't matter for me. :)
Any idea to improve it?
