 Calling `wp_delete_post( 2456, 1 )` does not flush the caches for the re-
 assigned posts. For example:

 {{{
 // assuming post 123 has an author of 2
 $post = get_post( 123 );

 wp_delete_user( $post->post_author, 1 );

 $post = get_post( 123 );
 $post->post_author; // this is "2", should be "1"
 }}}

 This is because `clean_post_cache` is not called on the reassigned posts
 (see http://core.trac.wordpress.org/browser/trunk/wp-
 admin/includes/user.php#L259).

 The best way around this I can see is get the post IDs and called
 wp_update_post() to let code hook in to update stuff where necessary. If
 performance is an issue (s wp_update_post can be slow), then I think it
 should at least get all the post IDs and call `clean_post_cache` on them.
