I just tried again without a tmpfs (actually, with
GIT_TEST_OPTS=--verbose-log, which matches Travis) and still got the
"prove" version as only about 10s faster. So I dunno. My disk is an SSD,
so that probably _is_ faster than Travis's disks, and maybe that would
matter.

I'm giving up on finding it. If you happen to have a recipe for
reproducing a larger speedup with "--state=slow,save", I'd be curious to
see it. But don't spend much time on it on my account. The existing
prove-caching setup is there and working, so even in the worst case if
it's not helping, it's not actively hurting much.
