I'm not too sure we should create a new fd; just use the same one
since sockets are supposed to be used that way.

I suspect, though, that using an entirely new connection could
simplify a few things (like the next patch).

In a private chat, Dave mentioned he'd give this some thought (and
give it a go) -- hope we don't end up needing to do things the dup
way.
