In this discussion we have not mentioned that OMS have put some thought
into the issue by implementing CopyOf, CopyFrom, and handling alias
pointers. All this was done within the implementation of Stores,
and thus it may not seem as general as the problems you are posing.
But it is worth mentioning that they did address the issue and they
provided a working solution.

Ironically, when we discussed it a while ago, both the problem and the
solution were considered too abstract by a certain mathematician whose
name starts with "R". I value his opinions. It tells me that maybe we do
not have to worry?
