Interesting, yes. I can't tell what to do right now. In XaAES there is  
something similar: It parses the content of the alert-text (CE_fa() in  
k_main.c):

   if( pid >= 0 && strstr( data->buf, "KILLED:" ) )
    {
      short s;
      long r;
      if( pid == C.Aes->p->pid || pid == C.Hlp->p->pid || pid ==  
C.Aes->tp->pid )
        return;
      for( s = 0; !(r=ikill(pid, 0)) && s < 666; s++ )
      {
        ikill(pid, SIGKILL);
        nap(20);
      }
      nap(2000);
    }

to be sure the app is really gone. But that is not very elegant.
