Comment (by nacin):

 Nope. $post->ancestors is only sometimes set, and (under 3.3) it is never
 set for a post object that comes from WP_Query. It *is*, however, set for
 the post object in cache (but not `$wp_query->posts[0]`) when is_singular,
 due to get_post_status() caching the object (as described above).
