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. |

Tests in this directory are compiled into the _testcapi extension. The main file for the extension is Modules/_testcapimodule.c, which calls `_PyTestCapi_Init_*` from these functions. General guideline when writing test code for C API. * Use Argument Clinic to minimise the amount of boilerplate code. * Add a newline between the argument spec and the docstring. * If a test description is needed, make sure the added docstring clearly and succinctly describes purpose of the function. * DRY, use the clone feature of Argument Clinic. * Try to avoid adding new interned strings; reuse existing parameter names if possible. Use the `as` feature of Argument Clinic to override the C variable name, if needed.
