 Replying to [comment:42 ryan]:
 > As a possible performance improvement for sites without a persistent
 object cache, do the get_post() array_map() only if $non_cached_ids and
 $ids don't have the same count? If they're the same just use $fresh_posts.

 Even with a non-persistent object cache, get_post() shouldn't trigger any
 new queries, since update_post_cache() is called before it.
