The new `tests/fixtures/commit-graphs` fixtures are built using the exact same set of commits each time even as their sources repos in `tests/fixtures/repos` get newer commits. My hope there is to make upcoming commit-graph benchmarks more consistent.

The purpose of this is to control concurrency. The preparation step should be done in parallel, cloning all repositories at the same time, but the actual stress test should run sequentially. If you see a more idiomatic or simple way to achieve this, I would be glad to see this as part of this PR. It might be time to refactor the stress testing facilities, after all they have grown organically and it might be time to factor them out. |

I have ran the stress test directly using fatal: malformed object name v5.8 |
|
In any case, thanks a lot! I believe this could be some local issue as I had a version of the linux repository locally, but possibly with only a partial/old pack that I use specifically for pack testing (1.3GB in size, more compressed than what github provides). Thus it should work once I get a fresh clone of the repo, and CI agrees. |

The new URL should trigger an overflow check but it only
happens when `url::Url::parse()` is called directly as our
code doesn't let it through anymore.
Here is the log from the fuzzer run as reported:
