summary:
gh-101758: Fix Refleak-Related Failures in test_singlephase_variants (gh-101969)
gh-101891 is causing failures under `$> ./python -m test test_imp -R 3:3`. Furthermore, with that fixed, "test_singlephase_variants" is leaking references. This change addresses the first part, but skips the leaking tests until we can follow up with a fix.
