There is another, robust way to do this: Make the parent process a group
leader with setpgid(0,0). Then `kill -9 -$$` will kill only the processes
started from that parent (or from children, recursively). Or use setsid to
create a session leader for even more robust killing (there is a setsid
command available to do this within shell scripts).

(You might not need this for your purpose, but I thought I would mention it in
case you at some point may want to run this in Buildbot or similar).
