CLHS 4.3.6

   "If a class is redefined in such a way that the set of local slots
    accessible in an instance of the class is changed, a two-step process
    of updating the instances of the class takes place. The process may
    be explicitly started by invoking the generic function
    make-instances-obsolete."

But why do you ask me? You did it yourself, on 2003-04-04 !
