This allows us to ensure a packet is read by the other end, but we don't read anything else from them or write anything to them. Using '+' is similar, but because it closes the connection, the peer might notice before receiving the packet (such as if it does a write). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
