+ * 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.
