    * A standardized prefix is useful to allow visual inspection of an APCu user

    * then if the caller does not provide a $site_path only the Drupal root will

    * Additionally, if a multi site implementation does not use site specific
    * module directories setting apcu_ensure_unique_prefix would allow the sites
    * to share APCu cache items.

    * @param $identifier
    *   An identifier for the prefix. For example, 'class_loader' or

    *   The prefix for APCu user cache keys.
