As I pointed out in my PR, "make -j4 buildworld" is more than sufficient
to demonstrate the problem.

I'll pull over 6.0-BETA1, rebuild the array (that is the time-consuming
part of this test - takes 6-8 hours for the rebuild to run) and see if it
fails during a buildworld.
Maybe I'm wrong, but in my tests I had the impression that RELENG_6
includes the phk's update to make which corrects the -j behaviour.
In 4.x and 5.x, every submake will spawn up to n tasks (n being the
number provided with -j), and a buildworld -j4 in UP hardware easily
produces a 2 digits system load.
That's not more the case with 6.x (if I'm not wrong), in my test
buildworld -j4 puts the load right near 4.
So I hope you have other ways to test the new ATA, as make buildworld
might not more be the monster it used to be.
