After we stop devd, /var/run/devd.seqpacket.pipe is being kept. Because no one is on the writing side, https://github.com/freenas/freenas/blob/master/src/middlewared/middlewared/plugins/device.py#L80 returns None immediately and devd_listen restarts immediately leaving asyncio no chance to execute other tasks. So, after devd stops, middleware hangs completely — it does not process incoming requests and also has no opportunity to terminate properly.

I think we can just add await asyncio.sleep(1) before break, or it is not there for reason?

Isso no reason to not do that but I am unsure of the problem. Shouldn't the "await read" and/or "await asyncio.open_unix_connection" give a chance for that to happen?

I am think the real problem here is that its looping non-stop because line = b'' and we should really change from "if line is None:" to "if line == b'':" or "if not line:" ?

William, you are absolutely right!

Vladimir: what is the target date for this one?

Dru: merged both in master and 11.1-stable
