 > Use wp_cache_add() instead of wp_cache_set() when priming the object
 term cache in update_object_term_cache(). Pass the real post_type to
 clean_object_term_cache() instead of hard-coding post. Call
 clean_object_term_cache() from clean_bookmark_cache(). Props leewillis77.

 This causes a notice in clean_post_cache() when it's called from
 wp_delete_post() and the post being deleted isn't in the cache. This is
 because get_post() will not return an object as the post no longer exists.

 PHP Notice:  Trying to get property of non-object in wp-includes/post.php
 on line 4368

 This is quite hard to reproduce under normal conditions as it is often
 masked by the post being in the cache at the get_post() call. Artificial
 reproduction is easy by calling `wp_suspend_cache_addition( true )` before
 wp_delete_post(). It also causes an error in the unit tests when WP_DEBUG
 is enabled.
