In <1990Aug17.133833.9024@siia.mv.com>, drd@siia.mv.com (David Dick)
talks about an even more elaborate version of the user/supervisor
mode division scheme, and illustrates some imaginative uses for
it.

Dear David, please reread <1252.26cbdffa@waikato.ac.nz>, where I tried
to make clear a point I first raised in the second half of
<1204.26c2fb48@waikato.ac.nz>. I am beginning to get the feeling
that there is a distinct "timesharing mentality" which is being
demonstrated by a large number of people, who have *great*
difficulty appreciating that a protection hole is a protection hole,
regardless of how you implement it.

I never thought I'd agree with this statement I keep sending up,
but: "To someone with a hammer, every problem looks like a nail."
