The buildbots show a refleak in test_super. I narrowed it down to this:

"""Unit tests for zero-argument super() & related machinery."""

import unittest


class TestSuper(unittest.TestCase):

    def test_attribute_error(self):
        class C:
            def method(self):
                return super().msg

        try:
            C().method()
        except AttributeError:
            pass


if __name__ == "__main__":
    unittest.main()

And found a fix. PR incoming.

   The buildbot run at https://buildbot.python.org/all/#/builders/75/builds/761 shows several other refleaks, but none of them reproduce on my branch with the patch from #104414, so hopefully that one is enough to get the bots clean.
