 If you create two separate, non-hierarchical post types, you can create a
 top-level post within both of them with the exact same slug. Yet, if you
 have two separate hierarchical post types, you can't.

 The problem is when it is hierarchical, {{{wp_unique_post_slug}}} also
 takes into consideration the post parent. Of course, two top-level posts
 would both have a post parent of 0.

 I understand that the post parent should be checked for child posts as
 they are under their parent's "tree". However, if there is no post parent,
 shouldn't that part be left out of the check query?
