Comment (by ryan):

 Core calls update_object_term_cache() strictly to prime caches, not
 propagate changes. Any plugin using this function to propagate changes to
 a post's relationships to the cache must be doing very naughty things like
 bare SQL queries.  In general, we prefer the delete/add model to the set
 model. So, the use of wp_cache_set() instead of wp_cache_add() here seems
 to be an unintended artifact.
