<h3>Log Message</h3>
<pre>Accept a post object in clean_post_cache(). Fixes <a href="http://core.trac.wordpress.org/ticket/20486">#20486</a>.
The post_type can then be accessed to properly clean the taxonomy relationships cache.
The full object is useful in situations when an ID might reference a post that has been
removed from the database (e.g. wp_delete_post()).</pre>
