Never set SO_REUSEADDR on a UDP socket.
The effect is quite different from TCP sockets.
For TCP, it allows you to listen for new connections even if there
are outstanding old connections with the same local address.
For UDP, it allows other people to steal your packets by
binding to the same address.
