   * from turning off.
   *
   * The resource manager defines what each topic means and sets policy.  For
   * example, the resource manager might decide to ignore 'screen' wake locks
   * held by pages which are not visible.
   *
   * One topic can be locked multiple times; it is considered released only when
   * all locks on the topic have been released.

   * The returned MozWakeLock object is a token of the lock.  You can
