Just wondering.. Is this simply a case of defensive programming or is it an error? (say, we're targeting only CPython). For instance, what happens when there's dictionary key with a custom __hash__ or __eq__ method? Its probably wise to simply use a lock and relieve ourselves of the burden of thinking about these cases. But it still is worth knowing... Regards Sreeram
