Michael:

The thread setup and cleanup is not required, AFAICT. You are also correct in that these particular test modules do not run correctly without modification (although test_queue does now that the bug I reported there was fixed).

Sorry by predicated, I mean that we could mask out the base classes that many of the tests are enumerated on top of. Some kind of decorator for the base could prevent the base class being discovered unless it's inherited from. This is the source of the errors one currently gets running the tests via -m unittest.

Eric:

I'm not sure what you mean by the files being long. I've taken the existing test case list and exposed this directly to both load_tests and unittest.main. The load_tests boilerplate is disappointing, but explicit.
