   * - For iterator(), we can accomplish that by not overriding iterator() at all. That way, we
   *   inherit an implementation that forwards to the delegate collection, which performs no
   *   holdsLock assertions.
   *
   * - For stream() and spliterator(), we have to forward to the delegate ourselves because
   *   ForwardingSet does not forward `default` methods, as discussed in its Javadoc.
