Comment 401 for bug 417757

I thought the obvious problem with this was addressed way up near the top in comment 20 when someone pointed out that using the same port for the IPv4 and IPv6 queries gave firewalls fits. Ulrich Drepper had one of his standard "purity over practicality" tantrums and refused to change it to use two different ports to accommodate dumb firewalls, but since Ulrich is gone now, perhaps saner heads could revisit that? (And perhaps revisit all other bug fixes rejected over the years by Ulrich? :-).
