 This is a continuation of #2904. On the first branch of that ticket
 (trac2904) the tests were changed to use IPv4 rather than IPv6, which was
 originally used as a work-around for that bug. The port number was changed
 in #2904 (branch trac2904_v3) but the IPv4 / IPv6 changes were not
 included. This ticket is to track that desired work. We need to make all
 of the feature tests in lettuce use IPv4, and then add in a suitable
 number of IPv6 tests to ensure that the IPv6 code-path is tested.
