Guido van Rossum added the comment: To find out what really happens, use pdb to step through the example. This gives much better insight than adding a printf() call to PyObject_Call(). I've notice myself when stepping through I/O that there are a lot of checks for closed -- this may have to do with the stacking text -> buffer -> binary though. I've also noticed overridden isinstance checks in abc.py being called, which surprised me slightly. I haven't had time to look into this further though.
