Here is an update with the quad buildworld tests on monster, with the
latest commit. Historical data. Note that I fixed the improvement
numbers, I was calculating them wrong. 100% improvement means half
the time.
Tests on monster (48 core opteron w/64G ram)

And with the latest commit today (on first run after boot even!)
:monster buildworld -j 40 timings 4x COMMIT#2: (108% improvement) <<<
3943.25 real 4630.76 user 21062.91 sys
And I expect to do better yet. Current system status: We have one
issue with a reproducable seg-fault/bus-fault related to mmap which
I hope to squash today.
