The details have changed.  The basic concepts haven't.  In fact, the *basic*
concepts change so slowly that reading Bach's book on the SYSV kernel or
McKusic & Liefler on the BSD kernel will teach you a lot.

In fact, I'll go out on a limb and say that reading how *other* systems have
solved the same issues is a Good Thing. Knowing just "Linux solved it this way"
is one thing, but knowing "Linux solved it this way, but BSD took a different
approach because X, and IBM's VM/SP did Y instead to avoid the issue entirely"
is a whole different level of understanding.
