Thank you for getting to this, Ned!
@ambv, this test-only fix should fix the failing Fedora buildbots.

No failures are in test_zlib except the s390x builds (like this one), which is expected: on s390x zlib-ng uses hardware acceleration, which makes the compressed bits different (but still valid).

AFAIK it's the same failures as any other 3.10 PR -- dbm crashes on GHA.

Then let's merge
