This unit test pretty much always fails on the Python 2.6 Windows builder:

Start with twisted/internet/test/test_tcp.py, especially AbortConnectionTestCase_Win32Reactor.test_resumeProducingThrows and runAbortTest. Read twisted/internet/test/reactormixins.py around runReactor, then run the failing test on the Python 2.6 Windows builder. Done means the test finishes without the reactor timeout and verifyReactorIsClean sees the expected delayed call.
