If I understand correctly, the reason that you need per-run setup is that your "git clean" command actually cleans things, and you need to restore the original state for each time-trial. Can you instead use "git clean -n" to do a dry-run? I think what you are timing is really the "figure out what to clean" step, and not the cleaning itself.
