Xiang Zhang added the comment: Raymond, In single threaded case popitem may still fail.
I want to correct my last message that popitem does not fail in this case because it calls __getitem__ but instead it calls __contains__[1]. In __contains__ it deletes the item since it expires, and finally emit a KeyError[2]. Even if it passes __contains__, it will call __getitem__[3].
