 * Invoke all remaining finalizers that haven't yet been run.  (Since the
 * notifier is not called, this should be called from a separate thread.)
 * This function is needed for strict compliance with the Java standard,
 * which can make the runtime guarantee that all finalizers are run.
 * This is problematic for several reasons:
 * 1) It means that finalizers, and all methods called by them,
 *    must be prepared to deal with objects that have been finalized in
 *    spite of the fact that they are still referenced by statically
 *    allocated pointer variables.
 * 1) It may mean that we get stuck in an infinite loop running
 *    finalizers which create new finalizable objects, though that's
 *    probably unlikely.
 * Thus this is not recommended for general use.
