- mpsc::Receiver::try_recv returns Err(TryRecvError::Empty) when closed with outstanding sender permits
- mpsc::Permit::send successfully delivers payload through closed channel
- mpsc::Receiver::try_recv returns Ok(payload) to drain the permit-delivered message
- mpsc::Receiver::try_recv returns Err(TryRecvError::Disconnected) only after all permits and messages are exhausted
