Yes.  But it doesn't help in the "tethered" case, where your "router"
(i.e., your cell phone) changes IP, but your laptop doesn't.

That's no reason not do write code to terminate all current TCP
connections if DBus says that we've changed IP (we should do that, too),
but it's not a complete solution.
