I think it is not a good idea to kill sub process. Because when we catch a
exception, we do not know whether sub process is still running. "kill pid" may
cause other error.
By the way, when parent process is exist, the sub process will exit when
read from stdin encounter a EOF, so sub process will not zoombie.
