You could do a lot of that by using a regular Intel 32-bit x86 architecture
chip the way the original designers of its security features apparently
intended: Put almost everything in its own segment, use the 4 rings to
give least privilege to code modules, use call gates, etc.
And you get quite a performance hit over the "unixy" way of using it.
But it could be a lot more secure.
