My take at improving the universe: allow the worlds to be

built in parallel.  Examples:

make universe
	Build worlds sequentially, each world sequentially.

make universe JFLAG=-j4
	Build worlds sequentially, each world in parallel.

make -j4 universe
make -j4 universe JFLAG=-j2
	Build four worlds in parallel, each world will be
	built in parallel too.  World parallelization is
	set to four in the first synopsis, and to two in
	the second.

make -j4 universe JFLAG=-B
	Build worlds in parallel, each world sequentially.

("world" == buildworld followed by buildkernels.)
