 According to the ticket 34292, dns-prefetch to s.w.org can be disabled
 with the following code (modified with the actual function):


 {{{
 function trac34292_example_resource_hints( $hints, $relation_type ) {
     if ( 'dns-prefetch' === $relation_type ) {
         return array_diff( $hints, wp_dependencies_unique_hosts() );
     }

     return $hints;
 }

 add_filter( 'wp_resource_hints', 'trac34292_example_resource_hints', 10, 2
 );
 }}}

 However this doesn't work. I still see the dns-prefetch in HTML.
