Splitting groups of tests to run in parallel via multiple processes is a pretty good use case.

Indeed, but it implies a lot of things about TestCase instances, which could have additional non-pickleable attributes (e.g. file objects). You'd better pickle the TestCase class instead, or simply the module name as we do with regrtest -jN.
