Yes, you are absolutely right, but that doesn't change the fact that many extensions are written as if innocuous function calls like PyList_SetItem won't context switch. It mostly works fine since custom destructors releasing the GIL are extremely rare.

"Mostly works fine."

I dunno, I'd rather have a reliable bug than a heisenbug.

Any class with a __del__() method is going to release the GIL. That's not uncommon. My intuition is that threaded Python is rarer than classes with a __del__() method.
