Comment:

 In 3.3 the $posts array in WP_Query can contain a post object with the
 ancestors property set. This is because get_post_status() is working on an
 object (reference) and that object gets the ancestors property set.

 I think that for 3.4 we should remove "->ID", see
 http://wordpress.org/support/topic/nest-page-ancestors-in-34-r3. There are
 still fewer queries run on a child page in 3.4 than 3.3 even with it
 removed. Then we can re-add it for 3.5 with lazy loading of ancestors.
