2011-07-07 Thread high bandwidth
I use cached dns lookups with pdnsd on my ubuntu machine to speed up web access as regular lookups can take 15-30 seconds. However, python's mechanize and urllib etc use socket.getaddrinfo, which seems not to be using dns cacheing or taking a long time because of ipv6 lookups. In either case, I sub
