-	 *
-	 * We work on 4 different 'bins' (implemented here as linked lists):
-	 *
-	 * * sorted:       the eventual list, in the order we wish to push
-	 *                 into the database.  This is the only ordered list.
-	 *
-	 * * parent_class: The current parent class 'bin' we are
-	 *                 trying to find subclasses for
-	 *
-	 * * subclass:     The subclasses we have found so far
-	 *
-	 * * unsorted:     The remaining objectClasses
-	 *
-	 * The process is a matter of filtering objectClasses up from
-	 * unsorted into sorted.  Order is irrelevent in the later 3 'bins'.
-	 * 
-	 * We start with 'top' (found and promoted to parent_class
-	 * initially).  Then we find (in unsorted) all the direct
-	 * subclasses of 'top'.  parent_classes is concatenated onto
-	 * the end of 'sorted', and subclass becomes the list in
-	 * parent_class.
-	 *
-	 * We then repeat, until we find no more subclasses.  Any left
-	 * over classes are added to the end.
