However, because Ztunnel operates only at Layer 4, we are in a tricky position:
* TCP is stateful, so we cannot really just pass state over to the other process.
  If we operated at L3 we could just start processing packets in the new Ztunnel.
* We do not operate at L7, so we cannot signal to the application, in any way, that it should reconnect (to the new Ztunnel).

Realistically, that means the best we can do is:
