Hrm. I understand the goal, but I'm not sure if that's achievable all the time in practice. For example, the particular unit test's whole point is to ensure that calling start_http_server() actually starts the http server on the port we expect it to be running on.

Two obvious potential workarounds for this are to dynamically choose a port to hopefully avoid conflicts, and to take out a lock on the port while attempting to run the test, but I can't think of a way to actually test this without it producing any visible effect at all. 

Other ideas?
