tests vulnerable to connectivity issues

[vbabiy]

Because the tests work with actual remote servers, it's common to see false positives (i.e. failures that aren't bugs) in my buildbot. It would require some work, but it should be possible to set up mock interfaces that allow us to test all this stuff without actually going out over the network.

Closing this as a duplicate of #259, since the description there reflects the work that was done in GSoC 2010 to address this (but inadequately, IMO).
