This is just a rant, not a question.
Suppose you have process A, which forks child B. Suppose process B exits, becoming a zombie. Then, process A exits without reaping child B. Child B is now re-parented to init, but since it is already a zombie, init never receives a SIGCHLD and thus does not reap the zombie.
Result? A zombie that you can't get rid of. I hate it.
