Who is actively working on ULE, getting feedback from users,
improving ULE, etc.?  I asked some questions about the
late tool used to evaluate ULE, and at first didn't get any responses,
but was finally directed to look at: http://www.chesapeake.net/~jroberson/late.tgz

I also mentioned on freebsd-arch that the following tool developed
at University of Utah might be useful for evaluating scheduler performance
on FreeBSD:
http://www.cs.utah.edu/~regehr/hourglass/

I know a lot of researchers who are interested in operating system
schedulers (especially for real-time systems), so leveraging off of their 
work couldn't hurt, and might lead to a better ULE implementation.
