This case could also be avoided by making it impossible to re-use a  
nic-hdl. I believe that is already the case for organisation objects.  
Putting it in place for person and role objects would probably be a  
good thing. But I doubt it's an urgent requirement and I wouldn't  
want to delay this cleanup.
