This is unorthodox and very MOP-py, but it seems to solve your problem (i.e. after defining this method, shared-initialize resets the instance to its initforms).

(defmethod slot-boundp-using-class ((class (eql (find-class 'foo)))
				    instance
				    (slotd standard-effective-slot-definition))
  (declare (ignore class instance slotd))
  nil)
