The parent information ((ppid,pid) pair) is useful for process group
aggregation while do_exit() hook is needed to save per task
accounting data before the task data is disposed.

The fork_connector is not designed to solve accounting data collection

The accounting data collection must be done via a hook from do_exit().
by the time do_exit() occurs the parent may have disappeared... you do
need to record something at fork() time so that you can account to the
correct ancestor.
an example of where this ancestry is useful would be the summation of all
cpu time spent by children of apache, spamd, clamd, ...
