As I understand it, Wendy is considering the case of a multi-homed
server. She wants to record the IP address on which we received the
datagram so that she knows which locks to invalidate in the case of a
migration of that particular IP address onto another server.

My point is that she won't get that information if the socket is bound
to INADDR_ANY, as would be the case for a UDP socket.
