We definitely have an issue with localhost. When forcing the DNS resolver to
return 127.0.0.1, we pass 1-16 then 17 fails as I expected to happen based
on my DNS futzing. Heads up that this test is not-surprisingly sensitive to
DNS problems. My environment is still in a messy state where I can reproduce
the original problem so it might be a useful moment for me to find a way to
modify the test script to harden it. Any suggestion on that score (as in
where and
roughly how it might be made more reliable)?

Note: Since the original post, I moved the fork to 2.4.0.
