New submission from Jeroen Demeyer <j.deme...@ugent.be>:

This is a memory leak:

>>> while True:
...    def f(): pass
...    f.__doc__ = f

This also:

>>> while True:
...     f = [].append                                                           
                                                                                
        
...     f.__module__ = f

This is because the classes "function" and "builtin_function_or_method" do not 
implement tp_clear.
