Summary: foo() doesn't use __getattribute__

Initial Comment:
In the Python 2.2 release notes, it says::

- For new-style classes, what was previously called
__getattr__ is now
  called __getattribute__.  This method, if defined, is
called for
  *every* attribute access.  

However, if I define a callable class that also defines
a __getattribute__ method, the __getattribute__ method
is not used when I say instance().

class Foo(object):

    def __getattribute__(self, name):
        print "__getattribute__ with name =",name
        if name=="__call__":
            return lambda:1
        object.__getattribute__(self, name)

    def __call__(self):
        print "__call__ method called"
        
f = Foo()
f.__call__()
f()

$ python /tmp/test.py
__getattribute__ with name = __call__
__call__ method called

I would expect the second line of output to be the same
as the first.
