I will back out the change, but I think you are making the 'universe' target
out to be more than was intended. We used to talk about tiers. We seem to have 
lost sight of that.

This isn't related to DTrace. It's more about what builds developers are
expected to do before committing stuff. Much of the buildworld breakage
over the last month would have been detected if a universe build had been
done. Even the current breakage.
