* Invoke all remaining finalizers that haven't yet been run.
* This 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 calle 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.
