I just realized that there is another reason to use setsid(), where
setpgrp() is applicable too: move the child into its own process group
and kill the whole group (child and its childs if any) then. I mean, use
the corresponding flag (which I proposed to add in [1]), which will
change :kill() behaviour.

So, it seems, we should do ioctl() + setpgrp() on Mac OS?
WBR, Alexander Turenko.
