Two test_multiprocessing_spawn.test_misc tests are still failing and requires more investigation:

  • FAIL: test_resource_tracker_sigterm (test.test_multiprocessing_spawn.test_misc.TestResourceTracker.test_resource_tracker_sigterm)
    test.test_multiprocessing_spawn.test_processes
  • FAIL: test_wait_result (test.test_multiprocessing_spawn.test_processes.WithProcessesTestCondition.test_wait_result)
