* [3.13] gh-113433: Automatically Clean Up Subinterpreters in Py_Finalize() ↵Miss Islington (bot)2024-06-261-9/+147
| | | | | | | | | (gh-121067) This change makes things a little less painful for some users. It also fixes a failing assert (gh-120765), by making sure all subinterpreters are destroyed before the main interpreter. As part of that, we make sure Py_Finalize() always runs with the main interpreter active.
