annotate Python/thread_cthread.h @ 21725:5d2bfbd47f1b legacy-trunk

A tentative fix for SF bug #503837 (Roeland Rengelink): type.__module__ problems (again?) This simply initializes the __module__ local in a class statement from the __name__ global. I'm not 100% sure that this is the correct fix, although it usually does the right thing. The problem is that if the class statement executes in a custom namespace, the __name__ global may be taken from __builtins__, in which case it would have the value __builtin__, or it may not exist at all (if the custom namespace also has a custom __builtins__), in which case the class statement will fail. Nevertheless, unless someone finds a better solution, this is a 2.2.1 bugfix too.
