I actually consider that an up side.  Sure it's inconvenient that you
can't delegate all such methods at once just by overriding
__getattribute__, but it would be more troublesome to *accidentally*
implement such methods because you implemented __getattribute__.  And
then there are methods that really should not be delegated in the
first place, like __del__.
