Dear Cafe,

I am using https://hackage.haskell.org/package/process-1.6.4.0/docs/System-Process.html... to start an external command, and wait for its completion.

If the process is hostile (e.g. fork bomb + countermeasures), then the *only* realiable way to do this is to use cgroups. Obviously, this applies to Linux only. I'm not sure there's actually any truly POSIX way to reliably kill hostile sub-processes. I don't think so. (The progress group thing doesn't work if the process is hostile. It'll work fine otherwise.) Regards,
