Comment:

 Actually, reading the ticket description, I now see this:

 > 2) first thing `wp_set_post_categories()` wants to know is `$post_type`
 and `$post_status`, for which it performs an SQL query, instead of getting
 this info from caller function

 Maybe a better approach would be to call `update_post_cache()` so that
 when `wp_set_post_categories()` runs it has access to to the `post_type`
 and `post_status` in the object cache?
