   *
   * Note regenerate+destroy should not clear the session data in memory
   * only delete the session data from persistent storage.
   *
   * Care: When regenerating the session ID no locking is involved in PHPs
   * session design. See https://bugs.php.net/bug.php?id=61470 for a discussion.
   * So you must make sure the regenerated session is saved BEFORE sending the
   * headers with the new ID. Symfonys HttpKernel offers a listener for this.
   * See Symfony\Component\HttpKernel\EventListener\SaveSessionListener.
   * Otherwise session data could get lost again for concurrent requests with the
   * new ID. One result could be that you get logged out after just logging in.
   *
   * @param bool $destroy  Destroy session when regenerating?
   * @param int  $lifetime Sets the cookie lifetime for the session cookie. A null value
   *                       will leave the system settings unchanged, 0 sets the cookie
   *                       to expire with browser session. Time is in seconds, and is
