https://github.com/HypothesisWorks/hypothesis/issues/3585 is reproducible on Python 3.10.10 but not 3.10.9, and so we suspect that https://github.com/python/cpython/pull/100922 may have introduced a (rare?) deadlock while fixing the data race in https://github.com/python/cpython/issues/100892. The downstream bug report on Hypothesis includes a reliable (but not minimal reproducer) on OSX - though it's unclear whether this might be an artifact of different patch versions of CPython on the various machines which have checked so far. <!-- gh-linked-prs --> ### Linked PRs * gh-102222 * gh-102234 * gh-102235 * gh-102236 <!-- /gh-linked-prs -->
