I am not sure we are able to build something simple if we try to 
implement it.

The easier way is to delay sending the kill signal to coordinator until 
all other kids has exited.  The coordinator process in this case should 
exit immediately after the kill signal received.

Or we can just delay sending kill signal to coordinator process for 1 
second. This is will give it enough time to exit later that the other kids.

The type of kids is not known by the master process. But I suppose we 
can find it using the kid name.

Any ideas?
