I have a note about mappings and address spaces pending, but before I send it I want to ask a naive question about the map operations:
Consider a sequence of operations in which
A maps to B B maps same stuff to C.
Is there some variant of the 'map' operation in which B does NOT retain the ability to revoke C's mapping? That is, in which the resulting mapping dependency hierarchy is
A / \ B C
instead of
A | B | C
That is, is there a way for a sender to give a receiver rights on data that are co-equal in all respects with those of the sender?
If not, is it important?
If such a "coequal map" operation existed, how often would it be used in contrast to the current map operation?
