These branches of computing history are really interesting.

> Domain/OS uses a single-level storage mechanism, whereby a program gains access to an object by mapping object pages directly into the process's address space.

It sounds similar in that respect to IBM i, and seems like an evolutionary branch that died off. What ever happened to this paradigm?

There was also KeyKOS and EROS. One problem with such systems is that data corruption can live forever if you're not careful (of course the same can happen with mmap which is our watered-down version of single-level storage).
