 * A base class for things which need to inherit from both TypedObject and
 * from ReferenceCount.  It's convenient to define this intermediate base
 * class instead of multiply inheriting from the two classes each time they
 * are needed, so that we can sensibly pass around pointers to things which
 * are both TypedObjects and ReferenceCounters.
 *
 * See also TypedObject for detailed instructions.
