Fixed missfeature pointed out by PJE. We do not quite provide

transparent Pythonic sematics for __setattr__ and __delattr__.
If these methods are implemented, then they *must*::

  self._p_changed=1 # prefered

or::

  self.__changed__(1) # if people get the heebe-jeebees from setting attrs

to manually register that an object's persistent state has changed, if,
in fact, it has.
