Serhiy, should I submit these fixes as separate patches? E.g. one patch for the warnings module, and another for the socket module?

More generally, should the items included in __all__ be derived from the items described in the documentation? For instance, only the functions listed in 18.1.2 https://docs.python.org/dev/library/socket.html#module-contents ?

And finally, should a unittest be added for both of these modules to ensure that __all__ includes all of the desired publicly exposed elements?
