This calls out to the provided make_tests helper to determine the

ConcurrentTestSuite provides no special mechanism to stop the tests

shouldStop attribute on the result object they are run with, which will
be set if the test run is to be aborted.
The tests are run with an ExtendedToStreamDecorator wrapped around a
StreamToQueue instance. ConcurrentStreamTestSuite dequeues events from
the queue and forwards them to result. Tests can therefore be either
original unittest tests (or compatible tests), or new tests that emit
StreamResult events directly.

calling startTestRun on this instance prior to invoking suite.run,
and stopTestRun subsequent to the run method returning.
