Intel had an wonderful processor for that, iAPX 432, and they botched it.

Every time I read about it I wonder how things would have turned out, if they managed to do a proper job with the CPU.

Don't forget i960 which had some of 432's fundamental protections with decent performance. It was used later in high-end embedded market.
