Didn't give it a thorough read, but I did see a section about the server
setting up a new socket, called a "connection socket".

Which isn't incorrect, but proves Grant's point rather well, that the
confusion is due to the overloaded term "socket". In that context, it's
speaking quite clearly of the "Python/C/Unix" concept of a "socket", and
not (as some other texts do) of the address/port combination.

To reiterate for 7stud, accepting a new "connection socket" does _not_
change the address or port from the originally bound "for-listening" socket.
