Multiuser protection does *not* cost a lot of code, *or* a lot of CPU. Consider that PDP-11 UNIX had it in the '70s, when the total size of the kernel was limited by hardware to 64K and there were variants that actually ran with 64K total, and with a sub-8088-class CPU. The code bloat in UNIX is due to creeping featurism, not resource management nor multiuser protection. -- Peter da Silva. `-_-' <peter@sugar.hackercorp.com>.
