As you say, when you restart a snapshot that was saved with
existing sockets (in any state), then the state of all these sockets
become invalideSocket when you restart the image. (That is
because the underlying OS sockets no longer exist.) Otherwise,
a socket should not become invalid unless you destroy it.

Yes.
