 * Hello,
 * I think I have found a problem with WP Super Cache cleaning expired files.
 * I use the mod_rewrite cache. So, when all pages are cached, of course there is
   not anymore calls to PHP files which could clean something.
 * So I have deactivated the wp-cron.php call in WordPress to make it manually by
   crontab.
 * While I have the cron calls which are working great now with the crontab, the
   WP Super Cache still not clean the expired files.
 * The crontab is called every 5 min, and the delay of expired files is 1 min.
 * I have looked at the plugin code trying to understand how this plugin works. 
   We can see that in wp-cache-phase2.php file, there is the function wp_cache_phase2()
   wich manage if the current viewed page should be cached or not, and only after
   that, activating the garbage colelctor.
 * The problem with this, if I’m right, is that calling wp-cron.php will never do
   something, because this page is never cached, and since the functions which are
   activating and scheduling the GC (wp_schedule_single_event) are called only if
   we are currently on a page which could be cached (if not it’s just return false
   and doesn’t move forward), it will never work.
 * Please tell me if I missed something or what.
 * Thanks
