Commencez par Lib/test/test_threading.py à InterruptMainTests.test_interrupt_main_subthread et par les chemins wait et start de Lib/threading.py indiqués dans le traceback. Reproduisez si possible l’échec du buildbot ARM64 macOS nogil, puis examinez le PR lié gh-118485 et la discussion associée. C’est terminé lorsque le test ne signale plus l’erreur de lock déverrouillé sans provoquer de régression du comportement de threading.
