The following vaguely hacky code might help:

class ParallelTestSuite(unittest.TestSuite):
    """Runs its tests in parallel threads"""
    def __call__(self, testResult):
        from threading import Thread
        threads = []
        for test in self._tests:
            result = test.defaultTestResult()
            thread = Thread(target=test, args=(result,))
            threads.append((test, thread, result))
            thread.start()
        for test, thread, result in threads:
            thread.join()
            testResult.startTest(test)
            for error in result.errors:
                apply(testResult.addError, error)
            for failure in result.failures:
                apply(testResult.addFailure, failure)
            testResult.stopTest(test)


(Most test result classes aren't thread safe, hence the complication of
 the above)
