i.e., one tells it more about what points to it, and the other tells
it more about what it points to.  (An interesting distinction in a
doubly-linked structure.  If you turn the Ent upside-down, does
inform become unify and vice-versa?)

Does it make sense to EVER freeze a DataStamp?  If someone can make
a virtual copy, why can't they make a real copy, then unify it?
What am I missing?
