a lot of python code has subtle race conditions where they assume some operations like dictionary access, manipulation, etc. are atomic and the GIL makes it all fine. remove the GIL and there can be a huge explosion of subtle and difficult to find bugs in even simple code. people have been working on trying to remove the GIL for a decade or more now and I don't expect any magic fix soon.
