The `_PySeqLock_EndRead` function needs an acquire fence to ensure that the load of the sequence happens after any loads within the read side critical section. The missing fence can trigger bugs on macOS arm64. Additionally, we need a release fence in `_PySeqLock_LockWrite` to ensure that the sequence update is visible before any modifications to the cache entry. |

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/
