Can't get Android tests to pass, but they should not be impacted by this change.

@incanus @1ec5 haven't pinpointed concretely where ios-memory-thread branches away from master but was able to scroll back over a month. Rebasing will solve this issue as it would include the fix in #7729.

Apparently @incanus branched off aeba7cc. That’s pretty ancient.

[incanus]

Oh weird! I thought I branched off of release-ios-v3.4.0. Let me adjust the PR.

[incanus]

Ok, now the base is the release branch and I rebased atop it just for good measure. 🤞 for tests again.
