Angus, I think you should change the continue into a break, otherwise you
won't 'move on' at all ;).

                        remove_it = true;

                } else if (waitrpid == 0) {
                        // Still running. Move on to the next child.
                        continue;

                } else if (WIFEXITED(stat_loc)) {
                        // Ok, the return value goes into retval.

Thanks, 
        Alfredo
