So you're talking about code that would make a C-implemented Python iterable of strictly C-implemented Python objects and then pass this to something C-implemented like list(..) or sum(..), while expecting no Python code to be run or signals to be checked anywhere while doing it. I'm not really convinced that such code exists. But if such code does exist, it sounds like the code is heavily dependent on implementation details.
Well, the OP specifically noted that he had recently encountered precisely that situation: """ I recently came across a bug where checking negative membership (__contains__ returns False) of an infinite iterator will freeze the program. """ Paul
