 * Fatal error: Cannot redeclare class WP_Object_Cache in /var/www/wordpress/wp-
   content/plugins/memcached/object-cache.php on line 93
 * When I enabled it per site there were no errors but it didn’t look like it was
   being used. This was based on the output of stats via telnet to localhost 11211.
 * Copying the file into wp-content crashes the sites of course.
