Ah, I was changing it to waiting for each child to finish in order to

I think your waitpid() is in the wrong place, and at least you need use
WNOHANG - unless you specifically want to wait for each child to finish
before starting another one.
But it still has the same problem, and I'm also trying to avoid
pcntl_wait or pcntl_waitpid at all because I still

You need to call pcntl_wait() or pcntl_waitpid().
Right, but if I do that, then the parent has to wait until the child
completes before it exits.
No it doesn't - just call

Hi Nathan/Torok...
Hey guys... got a bit of a question.
I'm playing around with the php/for/pcntl_exec functions and I've got
a process that spawns off a bunch of child processes. Unfortunately,
I'm getting to where I have 100's of zombie child processes that I can
