--------------------------+----------------------------
 In WP_Query, when a post is setup using `setup_postdata` /
 `generate_postdata` methods, the function `get_userdata` is called. If
 there are posts that are by multiple authors, this can result in a query
 per user / author.

 The function `cache_users` can be called and caches primed for all users
 in a single request.
