can we change it to a bash shebang instead? the bash looks less bad than the posix shell. I don't think it matters which shebang you choose exactly because I...
@rustbot author waiting for you to address the feedback and just change the shebang
better idea: just rewrite the test in rust instead: #121876

There was some confusion with regards to why `--no-allow-shlib-undefined` is passed at all. From a bit of experimentation it looks like both binutils `ld` and `ld.lld` do this by default....

no, I was just playing around so I didn't need one
I don't think the `Relaxed` ordering is correct here. The check could be reordered to after the construction or even later after the arena is used, causing two arenas to...
