[3.13] gh-118846: Fix free-threading test failures when run sequentially (GH-118864) by miss-islington · Pull Request #118927 · python/cpython

…ly (pythonGH-118864)

The free-threaded build currently immortalizes some objects once the
first thread is started. This can lead to test failures depending on the
order in which tests are run. This PR addresses those failures by
suppressing immortalization or skipping the affected tests.
(cherry picked from commit b309c8e)
