The next paper is an old but important publication in the history of operating systems. The paper

is A. Bensoussan and R. Daley, "The Multics Virtual Memory: Concepts and Design",

Proceedings of the Symposium on Operating Systems Principles, 1969." As usual, I would like a

summary, followed by a separate section containing your reaction. As I continue to read your

submissions, in many cases the summaries are better than the reaction sections, in the sense that

they were given more attention, or they are so commingled that I can't tell the summary and

reaction apart. Please physically separate the two sections (using 'Summary' and 'Reaction'

headings would be a good way to do that) and give some serious, critical thought to what you

have read.
