Comment (by scribu):

 Example usage:

 {{{
 $my_query = new WP_Query( array( 'tag' => 'foo' ) );

 update_post_thumbnail_cache( $my_query );

 while ( $my_query->have_posts() ) : $my_query->the_post();

   the_post_thumbnail();

 endwhile;
 }}}

 Well, actually, that would also cause an
 {{{update_post_thumbnail_cache()}}} call for the main query, which might
 be unnecessary.
