For the moment, I've tweaked the t/install-info-dir.sh test to make
it output more information that can be useful for debugging.  Could
you please re-run the test from the latest 'master' branch, see
whether it fails again (racily or reliably), and if so, get back to
us with the complete output?

Thanks,
