Process cannot become zombie if it's parent die, the "init" process
run "wait" for processes without parent, I think "external_program"
became zombie, not "csh". Try to use "exec" instead of "system + csh", e.g.:
if( $pid == 0 ) {
    exec "external_program";
}
so "kill 9 => $pid" in parent will kill external_process directly.
