Interesting.

USENIX itself takes a login/password pair for the paper. 
It seems there is an available copy at

http://wiki.bsdchat.com/Wiki.jsp?page=PDF

though.

Down the more (insane) scheduler games I've heard about is a 
Domain Specific Language for schedulers and runtime change of scheduler.
I might be able to find papers on that if it has interest, but it is
more language-theoretic research than usefullness probably.
