Relevant discussions for making PyMutex public in CPython for 3.13:

The second link notes some current alternatives, like PyThreadType_lock or platform-specific locks.

The C API working group decided to expose PyMutex in the C API https://github.com/capi-workgroup/decisions/issues/22#issuecomment-2155148479. We’re after the code freeze so it will take a special decision from the release manager for it to be included in 3.13 but it will definitely be in 3.14.

PyMutex, PyMutex_Lock(), and PyMutex_Unlock() are now public in 3.13 (will be available in beta 3).

Also the critical section API (i.e., Py_BEGIN_CRITICAL_SECTION() is now available publicly)
