Yup.
For example, the seemingly harmless dictionary item assignment can call back into Python for a custom type's hash and eq methods, so could it be that a thread switch could actually occur during this statement:
foo[bar] = baz if 'bar' has such custom methods? Maybe I'm wrong, and the GIL is still held in such a case, but I'm not sure how.
No, it isn't.
