[issue42536] Iterating on a zip keeps objects alive longer than expected (test_itertools leaks sometimes references)

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

Would it be possible to push a quick & dirty workaround for test_itertools? I'm getting more and more buildbot Refleaks failures.

For example, always skip TestGC.test_zip() for now.

This issue seems quite complex and I would prefer to have time to think about it to design a proper fix, rather than having to work under pressure.
