Comment (by nacin):

 Here's a quick patch that breaks all over the place but could be a good
 starting point for someone wishing to solve this.

 Essentially, here's what we currently do:
  * Query all posts
  * Group them based on ID and post_parent
  * Begin rendering posts until we've reached the total to display per page

 What we should do instead:
  * Query all IDs and post parents
  * Group them
  * Figure out what posts we need to grab to display the right number on a
 page
  * Use _prime_post_caches() to pull those specific posts into cache
  * Render those posts

 Querying all IDs and parents still isn't ideal, but it's a step in the
 right direction. Without MPTT this is not easy.
