Modules are modules, right?  That is, pickle.py and cPickle.so are both
represented as module objects at runtime.  A C extension can call
PyModule_GetDict() on any module.  If so, then any extension module can
add names to the __dict__ of any Python module.  The problem is that
modules expose their representation at the C API level (namespace
implemented as PyDictObject), so it's difficult to forbid things at the
C level.
