| Oh, this change does not work as expected, it does introduce a crash, see: It seems like the commit eb4e2ae (bpo-39877) introduced a race condition. |

Clear the frames of daemon threads earlier during the Python shutdown to call objects destructors. So "unclosed file" resource warnings are now emitted for daemon threads in a more reliable way. Cleanup _PyThreadState_DeleteExcept() code: rename "garbage" to "list".
