You just explained a bunch of implementation details but at the end of the day my point remains: having the GIL makes it easier to write parallel code. I didn't say it magically makes everything threadsafe.

It does not. What it does is create a bigger trap, because the code looks to be working in more testing situations, and will be more difficult to debug when it starts failing.
