 From what I can see

 {{{
 _prime_post_caches
 }}}

  does more harm than good when querying a large set of posts, and using
 the memory object cache.

 There should be a check with
 {{{
 wp_using_ext_object_cache
 }}}
  and possibly a filter to override the behavior so this only takes action
 when object cache is in use.
