Oh, my change on PyThread_set_key_value() has an unexpected effect on _testcapi.run_in_subinterp(): it now fixes the Python thread state. Py_NewInterpreter() creates a second Python thread state for the current thread, but PyThread_set_key_value() ignored the second call setting the new thread state. It's a little bit strange that nobody noticed this bug before. It doesn't fix issue #10915: test_threading still hangs when tracemalloc is enabled (I modified manually test.support.run_in_subinterp() for a manual test). This issue should now be fixed.
