 I believe (unless I am not using it correctly) that there is a bug with
 the new apply_filters_ref_array() function. Particularly, I am applying
 two different functions certain 'posts_' filters in the query, and only
 the one with the highest priority is processed. Small example:


 {{{
 function posts_where_filter_one($where) {
   global $wpdb;
   $where .= " AND $wpdb->posts.post_type = 'post'";
 }
 add_filter('posts_where', 'posts_where_filter_one');

 function posts_where_filter_two($where) {
   global $wpdb;
   $where .= " AND $wpdb->posts.post_status = 'publish'";
 }
 add_filter('posts_where', 'posts_where_filter_two');
 }}}


 You would expect $where to end up as:

 AND wp_posts.post_type = 'post' AND wp_posts.post_status = 'publish'

 But instead it end up as:

 AND wp_posts.post_status = 'publish'
