quite contrary. i think our build system is nice and polished, but sucks wrt 
speed. it runs down the tree multiple times. that's just evil. here, figuring 
out that nothing has to be done (make quickworld after make quickworld) needs 
several minutes. with a complete dependancy graph, this could be figured out 
in seconds (see kernel make).
