Comment:

 it is still buggy even in 3.7. today i've got out of sync
 category_hierarchy option - some categories were missing from wp_option
 'category_children' entry
 Current code:
 {{{#!php
         $children = get_option("{$taxonomy}_children");
         if ( is_array($children) ) return $children;
 }}}
 will not refresh hierarchy if it not empty. even with last patch.
 i suggest to switch to some caching solution implemented in wp core or get
 rid off this strange piece of code.
