 {{{wp_list_pages()}}} takes a {{{post_type}}} argument (it works with any
 hierarchical post type). {{{wp_list_pages()}}} is powered by
 {{{get_pages()}}}. {{{get_pages()}}} has object caching. When a Page
 changes (edit, create, delete), this cache is cleared, via
 {{{clean_post_cache()}}}. But it is '''not''' cleared for non-Page post
 types. Thus you get stuck with old data.

 Here's the offending code:

 {{{
         if ( 'page' == $post->post_type ) {
                 wp_cache_delete( 'all_page_ids', 'posts' );
                 wp_cache_delete( 'get_pages', 'posts' );
                 do_action( 'clean_page_cache', $post->ID );
         }
 }}}
