Force python mechanize/urllib2 to only use A requests?

Here is a related question but I could not figure out how to apply the answer to mechanize/urllib2: how to force python httplib library to use only A requests

Basically, given this simple code:

#!/usr/bin/python
import urllib2
print urllib2.urlopen('http://python.org/').read(100)

This results in wireshark saying the following:

  0.000000  10.102.0.79 -> 8.8.8.8      DNS Standard query A python.org
  0.000023  10.102.0.79 -> 8.8.8.8      DNS Standard query AAAA python.org
  0.005369      8.8.8.8 -> 10.102.0.79  DNS Standard query response A 82.94.164.162
  5.004494  10.102.0.79 -> 8.8.8.8      DNS Standard query A python.org
  5.010540      8.8.8.8 -> 10.102.0.79  DNS Standard query response A 82.94.164.162
  5.010599  10.102.0.79 -> 8.8.8.8      DNS Standard query AAAA python.org
  5.015832      8.8.8.8 -> 10.102.0.79  DNS Standard query response AAAA 2001:888:2000:d::a2

That's a 5 second delay!

I don't have IPv6 enabled anywhere in my system (gentoo compiled with USE=-ipv6) so I don't think that python has any reason to even try an IPv6 lookup.

The above referenced question suggested explicitly setting the socket type to AF_INET which sounds great. I have no idea how to force urllib or mechanize to use any sockets that I create though.

EDIT: I know that the AAAA queries are the issue because other apps had the delay as well and as soon as I recompiled with ipv6 disabled, the problem went away... except for in python which still performs the AAAA requests.
