Thanks,  I am working on some changes to improve SMP load balancing.  I'm 
going to test them more thoroughly on an array of machines that I have 
here before I commit them, but I'll let you know when I do.

In the future, it's more useful to do performance comparisons without 
WITNESS or INVARIANTS enabled as these options may unfairly hinder one 
scheduler or the other.  However, I don't doubt the relative results you 
present.

Thanks,
Jeff
