WebIn CPython, the global interpreter lock, or GIL, is a mutex that protects access to Python objects, preventing multiple threads from executing Python bytecodes at once. The GIL prevents race conditions and ensures thread safety. A nice explanation of how the Python GIL helps in these areas can be found here. WebThese threads share state that is protected by instances of Lock, which are themselves not fork-safe. The driver is therefore subject to the same limitations as any other …
