Note that if you have gobs of RAM, your content will be served from
memory even with regular mod_disk_cache (no ram disk) since the OS
will have everything in buffer caches.  (And you might need to be
careful about RAM disks, since they may or may not support sendfile().
 Giving up sendfile could be a big hit.)
