[issue30675] test_zipfile leaks references on Python 3.5 on the wo Refleaks buildbots (Gentoo, Windows)

STINNER Victor added the comment: I tested: "./python -m test -j2 -R 3:3 -m test_random_open test_zipfile" now pass on 2.7, 3.5, 3.6 and master branches. So this issue is now fixed. By the way, bpo-30776 should reduce even further false positive when hunting reference leaks. --

STINNER Victor added the comment: It seems like Python 3.6 and master (3.7) are not impacted by this bug, thanks to my rework on regrtest (now libregrtest) in Python 3.6. It's unclear to me if Python 2.7 has the bug: I don't see the warm_caches() function. --
