Comment (by markjaquith):

 Workaround for plugins that have hierarchical post types and use
 get_posts() or wp_list_pages():

 {{{

 add_action( 'clean_post_cache', 'YOUR_PREFIX_clean_post_cache', 10, 2 );

 function YOUR_PREFIX_clean_post_cache( $post_id, $post ) {
         if ( 'YOUR-POST-TYPE' === $post->post_type )
                 wp_cache_delete( 'get_pages', 'posts' ); // See:
 http://core.trac.wordpress.org/ticket/21279
 }

 }}}
