The computed time is already quite cheap, so I'm not much worried about that, FWIW. > We could also add entropy if we see a change in the node->type value for > non-NULL variants. I am not sure to get this one. The issue shows up if we have the same Node computed successively as reported on this thread. It would still be a problem for different node types, though less likely, when two nodes use with similar fields. -- Michael
