Sorry guys, I didn't get through the whole thread, but I wanted to say
just one obvious thing: if your program works correctly, then it is
*very* difficult (if not impossible) to create and leave zombies
around. If the program that fork()s does call wait() properly, no
zombies can remain anywhere. A zombie is just a process which has died
and is waiting there for its parent to call the damn wait().

If your code leaves zombies, then it is not working properly, and you
should fix it before moving on.
