I've always thought it would be nice to have a stripped-down
version of make universe (make galaxy?) that compiled for a
representative sample of platforms, and with only one or two
kernels per platform instead of 3 or 4 or 5. For small changes,
this represents a better tradeoff in time spent compiling vs. the
cost of things breaking occasionally. For actively developed
platforms, breaking the build wastes lots of people's time; for
everything else, there's tinderbox.
