Comment(by nacin):

 I don't have a problem with [13923], but I fail to see how the example in
 the inline docs doesn't handle this without feeling like a hack:
 {{{
  * Functions that are not pluggable (not wrapped in function_exists()) are
 instead attached
  * to a filter or action hook. The hook can be removed by using
 remove_action() or
  * remove_filter() and you can attach your own function to the hook.
  *
  * In this example, since both hooks are attached using the default
 priority (10), the first
  * one attached (which would be the child theme) will run. We can remove
 the parent theme's
  * hook only after it is attached, which means we need to wait until
 setting up the child theme:
  *
  * <code>
  * add_action( 'after_setup_theme', 'my_child_theme_setup' );
  * function my_child_theme_setup() {
  *     // We are replacing twentyten_setup() with my_child_theme_setup()
  *     remove_action( 'after_setup_theme', 'twentyten_setup' );
  *     // We are providing our own filter for excerpt_length (or using the
 unfiltered value)
  *     remove_filter( 'excerpt_length', 'twentyten_excerpt_length' );
  *     ...
  * }
  * </code>
 }}}
