But if the system saves state after it's buggered itself but before it

state.
They have solved these problems. It really doesn't happen like that. The
idea is that this system is extremely reliable. It doesn't get wedged.
Yes, according to the KeyKOS pages, just before the state is saved it does a self check to make sure that everything is as it should be. The only time (only one time) a buggared state got saved was when they were hacking and testing a new kernel. Apparently they got that ironed out really quickly. (Although, that's not to say that it /couldn't/ happen again.)
Finally... what use is fine-grain access control when the program can simply
demand total access and refuse to do anything until it gets it?
Why would you want to run such a malicious program? Software written for
this sort of system would not do that.
I agree. Any program *demanding* total access is probably suspect anyway. And anything that it comes packaged with which refuses to run without said needy program is equally suspect. Lots of whinedoze users still have no clue that the spyware on their systems got installed when they clicked on "I agree" in the EULA of the games they wanted to play.
