Looks like we have a refleak somewhere in the system that is exposing.

The following code exposes the refleak:

    def test_refleak(self):
        T = typing.TypeVar('T')
        class C(typing.Generic[T], typing.Mapping[int, str]): ...

The change that first triggered the leak is 8f0df4db2b06.

I'm not an expert in, but I suspect that the real bug must be somewhere in CPython core.

Guido, do you have any idea how 8f0df4db2b06 could trigger this?
