Each of the individual file names becomes a permanent part of the API. Even future additional splits are precluded because it might break someones dotted import (i.e. not a single function can be moved between those files -- once in unittest.utils, alway in unittest.utils). > Can Python 2.7 pickles containing unittest classes be unpickled using > 2.6 or earlier?

Yes, since unittest.TestCase is still available (as are all the names). I believe so anyway...

unittest.TestCase is not really pickleable. There were test_multiprocessing issues because of that (see recent SVN checkins).
