Just found this when refactoring some code 😅

"--pantsd-pailgun-port",

https://github.com/pantsbuild/pants/blob/ae25955e7e0aaf1aa8084ed68bd28ebe6e5b7f5d/src/python/pants/option/global_options.py#L895

nailgun (original) should have been jailgun, current should be railgun, and then that fully explains pailgun

that sounded like a pun, but I got it after the third read through 😂

If it's not obvious, it really is a failgun
