1. What do dualstack browsers do when the second connection opens?
2. ssh could complete authentication on the second connection and
then immediately close the connection - but this would trigger many
side effects on the server, and be a nuisance at the very least;
consider when a server requires token interaction to login, and
having a sliding window with some limited number of logins per day.
I personally don't really want the client to open multiple
connections when I only specicy one server.
