Heavy parallel make throughput is still down a little over 10%, but X
choppiness is markedly improved. Test-starve is now working. One thing
that I noticed is that irman takes quite a bit longer to complete than with
stock. I've attached the results of that, plus some contest numbers. My
local variant of contest has a couple of differences to stock: dbench
doesn't run so many instances, and list_load is just a small tree being
md5summed. There are two additional loads as well. ab_load is an ancient
apache bench jabbering with an also ancient apache (boring static page via
localhost)... you can guess what irman2_load is :)
