I found it in Google Groups. Search for "mailing.freebsd.current Lambert kmem_map" and you will find several good articles. It's really worth reading the entire threads to get a better understanding of how all of this works. The one I was referring to was at: http://groups.google.com/groups?q=mailing.freebsd.current+Lambert+kmem_map&start=10&hl=en&lr=&ie=UTF-8&selm=bde8n6%244jb%241%40FreeBSD.csie.NCTU.edu.tw&rnum=12 -- R.
