 1. Register a custom taxonomy, and create one or more posts associated
 with this taxonomy
 2. Place the attached code in your theme's functions.php [Tweak the args
 to get_posts accordingly to retrieve the posts created in (1)]
 3. Load your blog and inspect your error log.

 The output should confirm that while wp_suspend_cache_additions() blocks
 most cache additions, cache entries are still added for
 {$taxonomy}_relationships. E.g. in my case, the output is:


 {{{

 }}}

 As you can see entries have been added to the cache for the various
 {taxonomy}_relationships.

 This appears to be either because the call to wp_cache_set inside
 update_object_term_cache() in taxonomy.php should be wp_cache_add - and/or
 wp_cache_set should check the value of wp_suspend_cache_additions() before
 adding to the cache.
