      Description

      This is a memcache specific issue as memcached provides the prefix option.

      There have been reports of our cache keys colliding with Drupal cache keys when both are set to use the same memcache instance.
      Without confirming it I believe it makes good sense to include a Moodle specific prefix to avoid such collision with any software.
      We hash our keys as do many others so no doubt there is the chance for collisions.
