Python already has mutex and rwlock in its standard library IIRC. That's because the GIL only prevents races at the individual opcode level, not complex objects.

you are right, I forgot that, but I cannot find the RwLock in std lib https://docs.python.org/3/library/threading.html

My memory failed me. While mutex is part of the stdlib, the read write lock I used was part of a PyPI package.
