> Executing arbitrary setup functions while creating new processes is
> dangerous as all functions called have to be async safe. As setup
> functions are used for only very few purposes (setsid, chdir, monitoring
> and killing a process (see upcoming review) it makes sense to support
> them safely via parameters to subprocess.
> Another common use of child setup are is to block the child while doing some
> work in the parent. This pattern can be more cleanly expressed with
> parentHooks.
