Just FYI the process group lifetime ends with the last process exitting
it's group. Otherwise there could be all kind of races in the case when
you send the SIGTERM signal to the whole group, e.g. if the leader got
the signal first the rest of the processes may not be terminated if the
group lifetime ended with the leader...
