This is what I would expect. As long as the parent is running child
processes are attached to the process group's controlling terminal and
will be detached automatically when the parent is terminated.
Normally, the parent should wait (waitpid) for its childs to prevent
them of becoming orphans. Are you waiting for them?
It would be easier to help if you would let us know what the exercise is.
