 * I’ve been running Memcache for W3 Total Cache for quite some time, and recently
   my web host enabled APC and i thought I’d give it a try. I enabled it for Page
   Cache and began to get hundreds of errors, similar to this:
 *     ```
       Warning: require_once() [function.require-once]: Unable to allocate memory for pool. in /home/xxxx/public_html/wp-content/plugins/w3-total-cache/inc/define.php on line 1449
