Bug report
When running./python -E -m test --timeout=2700 -R3:3 -u-cpu -j40 test_free_threading.test_monitoring -F, I get a failure every ~50-100 test runs:
0:00:36 load avg: 122.12 [ 55/1] test_free_threading.test_monitoring failed (reference leak)beginning 6 repetitions. Showing number of leaks (. for 0 or less, X for 10 or more)123:456XX. 243test_free_threading.test_monitoring leaked [2, 4, 3] memory blocks, sum=9I think the issue is that we rely onThread.is_alive() instead of joining the threads. I think there are still some objects that may not be freed until the thread is joined (like the handle):
