Comment (by nacin):

 Just a thought:

 {{{
 class Nacin_Cache_Thumbnails_for_Queries {
    public $loops = array();
    function __construct() {
       add_action( 'loop_start', array( $this, 'loop_start' ) );
       add_action( 'loop_end', array( $this, 'loop_end' ) );
       add_action( 'begin_fetch_post_thumbnail_html', array( $this,
 'fetch_thumbnail' ) );
    }
    function loop_start( $query ) {
       array_push( $this->loops, $query );
    }
    function loop_end() {
       array_pop( $this->loops );
    }
    function fetch_thumbnail() {
        $query = end( $this->loops );
        update_post_thumbnail_cache( $query );
    }
 }
 new Nacin_Cache_Thumbnails_for_Queries;
 }}}
