`drop_gil()` assumes that its caller is attached, which means that the current thread holds the GIL if and only if the GIL is enabled, and the enabled-state of the GIL won't change. This isn't true, though, because `detach_thread()` calls `_PyEval_ReleaseLock()` after detaching and `_PyThreadState_DeleteCurrent()` calls it after removing the current thread from consideration for stop-the-world requests (effectively detaching it). Fix this by remembering whether or not a thread acquired the GIL when it last attached, in `PyThreadState._status.holds_gil`, and check this in `drop_gil()` instead of `gil->enabled`. This fixes a crash in `test_multiprocessing_pool_circular_import()`, so I've reenabled it. |

The Python C API ================ The C API is divided into these sections: 1. ``Include/``: Limited API 2. ``Include/cpython/``: CPython implementation details 3. ``Include/cpython/``, names with the ``PyUnstable_`` prefix: API that can change between minor releases 4. ``Include/internal/``, and any name with ``_`` prefix: The internal API Information on changing the C API is available `in the developer guide`_ .. _in the developer guide: https://devguide.python.org/c-api/
