I think it does, but that's not the issue: if the interface goes down all the temporary address are gone for good, not just "expired".

If you're on a stable address, and the interface goes down, will it let your connection/socket continue to exist?

Because if the connection/socket gets lost either way, I don't really care if the IP changes too.

I'm not sure what happens to the socket, maybe it's closed and reopened, but with this patch I have SSH sessions lasting for days with no issues. Without it, even roaming between two access points can break the session.
