Possible contrast & compare: the presentations on OpenBSD's network stack at http://openbsd.com/papers/

The first relevant-seeming presentation is from 2009[1] and doesn't really get into the pitfalls of low-latency switching/handling like this article does.

I'm definitely interested to see how other operating systems handle this, though. In particular: Windows (is networking in user-mode?) and Solaris-likes.
