You've got class instance variables which (unlike class variables) aren't shared around the inheritance hierachy at all. This is a slightly murky area which I wrote a bit about here: http://www.spacevatican.org/2008/8/19/fun-with-class-variables Searching for class instance variables should also turn up some interesting reading material.
