This makes signalling priority 6 so it can push commands before the
stream channel, without this the stream channel may be schedule
first and cause the signalling commands to timeout while waiting a slot.

v2: Return error if writes fails since that probably means the socket has been
disconnected, also makes code setting socket to blocking a bit cleaner.
