in thread Communicate with child process via stdin, stdout

Dunno... I have encountered zombies with a parent-PID of “1.” Dunno why it happens and I don’t think it should, but, “there they were.” I have only seen it in a FastCGI process (owned by Plack), but I have seen it nonetheless. It probably is a good idea, then, to clean up after oneself explicitly. If you rendezvous with every child-process that you created, and show them to their graves, then everything is nice and neat and predictable.

The OS re-parents a process to the init process (PID 1) when a child process is still running at the time the parent has gone away. This is entirely different from the situation above, because when you're dead you yourself can no longer wait for your children anyway.	[reply]
