I just fixed a regression in the load balancer.  On my 8way opteron ULE is 
now 22% faster than 4BSD for select-key.smack with 32 threads.  This is 
for both KSE and libthr.  libthr is of course significantly faster 
overall.  I believe I can improve this even more by borrowing some tricks 
from solaris.
