With this patch, I see this behavior:

cpython feature/http-server-bind-ipv6 $ ./python.exe -m http.server --bind localhost                                                                                                     
Serving HTTP on ::1 port 8000 (http://::1:8000/) ...
^C
Keyboard interrupt received, exiting.
