On pypy the subordinate LED objects in RGBLED composite objects do die on failed construction ... eventually. Unfortunately it's not quick enough to prevent the following tests from failing. As we can't know for certain exactly which test is going to follow, it's best to simply clear down the reservation table before each test.
