I’m a bit disappointed to see that the files after the change are as long.  I hoped we could avoid explicitly listing test cases, thanks to auto-discovery of TestCase subclasses combined with skips for specific platforms or optional modules.  Of course this would remove the possibility to run things like “../../python test_shutil.py” (and I do use these kinds of calls to run tests from my editor all the time), forcing us to always call “./python -m unittest test.test_shutil”.  Michael, do you think this should go to python-dev or do you disapprove (or think people will disapprove)?
