It defines any actions you want to happen after each round of tests that
should not be timed. Usually that would mean any action that resets a
modified repository to its original state. I'm not really sure about
the name, but test_perf_with_cleanup seems good to me.

Yeah, that was my first thought too, but as you explained that's not
possible. Just thinking out loud, we could drop the prerequisite check
for performance tests, as no performance tests currently use it. Future
performance tests may use it though and it would be inconsistent with
the rest of the test-suite.

I think this makes most sense. The cleanup part would only be needed
for the perf tests, but the flexibility of this wouldn't hurt. The
cleanup would then look something like this:

I'll try to send an updated patch series, probably over the weekend with
this suggestions included (It's time to go to bed now).
