There's a bug here. You need to return the module object you got from calling 
self.orig(). By the way, you really should follow my example of getting the 
.__name__ from the module object instead of the argument in order to properly 
account for relative imports inside packages. __import__() will be passed the 
relative name, not the fully-qualified name.
