Python gets a "Developer-in-Residence"

I don't think that's talking about "rerunning until it passes", but rather "if the test suite determines you may have affected it, it no longer takes more than a minute". But there are tests that are useful to "rerun until pass or N failures" (in one project I work on, context menus are opened which are display manager modal in X and serializing the tests is not feasible as it'd easily make the test suite take 5x longer to run). Tests involving inter-thread communication are better to "rerun until failure or N passes" though.
