FYI, lottery scheduling has already been implemented at least
twice for FreeBSD. For an example, see
http://www.csua.berkeley.edu/computing/software/lottery-sched.html
The code has not been maintained, apparently due to a lack of
interest, and it incurs a high scheduling overhead. Note that the KSE
work is likely to bring significant changes to scheduling in FreeBSD,
possibly causing you headaches later. You might also be interested in
Luigi's work on a PS scheduler; check the list archives.
