Not a fan. If you look around you can find SunOS 4.x sources, not legal but it is out there. If you read the SunOS vm code enough, it will come into focus for you. The code matches what you think a VM system should be. If you read the Mach code, nope, it's a tangled mess, there is no clear picture there. I read the papers and wanted to believe it was good, it is not.
