This should make restarting CI processes on Mac much more reliable, as Nomad cannot reliably kill the whole tree itself there. This should also solve the annoyance of CI jobs leaving behind running build containers when they are killed.
The behaviour relies on any long-running processes in the CI scripts being wrapped in a short_timeout or long_timeout call, which I think they all are.
Draft because I've not tested this yet.
