    HandleRegistries are like Registries, in that they watch for the death of

    a registered object. However, they send a self-change notification, passing the registered

    handle as argument, instead of creating a shallow copy and letting it do the finalization.

    Use Registry for objects which know themself how to clean up;

    use HandleRegistry, if someone else does the cleanup.
