computer memory as a virtual reality

[Raoul Duke]

what if the c++ things thought they owned memory on the stack&heap but it was actually all running on another layer of abstraction, a database, a virtual layer that is actually a single big persistent data structure, faking the evil shared mutable state that the c++ crap breathes. then the system could move toward enabling things like hot code swapping; time travel debugging; suspend&resume; etc. could it additionally impose some oracular concurrency ordering to get more determinism a la deterministic dataflow? then also could other programming languages/paradigms interface with that runtime and interop after a fashion with the c++?
