Great work!
Nonetheless I feel that the last few changes nerf a quad-core machine
way too much; you are killing 50% of what you gained in the -j48 case
for buildkernel and even worse than in the original case with -j4, which
is the most common case. buildworld -j8 on test29 also loses 50% of the

I´ll create a new thread about this as soon as a I can give it a
