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?

This was how Multics was designed too. It was one of the important features left out when Unix was written, because it was very hard to do on a PDP-7.
