Commit a793037d803abf098d172f686e2b95d27863c54d is not related to this issue. It skips the tests that were failed due to other side effect of COUNT_ALLOCS -- it makes type immortal. This is not a problem in 2.7 since all types are immortal in 2.7.

But there is other patch in issue19527: 00141-fix-tests_with_COUNT_ALLOCS-v5.patch. It was not committed since issue23034 provided better solution. You can try to backport it to 2.7, but this will just complicate the testing code for almost no benefit. Nobody wanted to do this. It was a decision to ignore this issue in Python 3.5 and earlier.
