Ok, so there's an issue with that condition: it can't be upholded on non-GC objects. Creating a non-GC object is quite obscure and rare, though, since it requires basically a class with no dict and an empty slots: [...]
One more problem, albeit minor: there's a test_descr failure in some part marked as "CPython implementation detail":
====================================================================== FAIL: test_subtype_resurrection (test.test_descr.ClassPropertiesAndMethods)
Traceback (most recent call last): File "/home/antoine/cpython/finalize/Lib/test/test_descr.py", line 3749, in test_subtype_resurrection self.assertEqual(len(C.container), 1) AssertionError: 0 != 1
However, the third-party test suites (Tornado, Tulip, SQLAlchemy, Django, zope.interface) show no regressions.
Regards
Antoine.
