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.)
