I talked to the Travis people, and it's just a limitation of the virtualization software they're using, that it reports the underlying hardware number. This suggests that maybe there should be a CPU=N argument to the top-level Makefile to control how many processors `raco setup` uses. Annoyingly, this can't be detected from the -j argument to `make` [1].
