Yep. That's one way to do it or you could just send a stop signal so the child processes won't waste your memory for nothing. Just replace for(;;)
with kill(getpid(),SIGSTOP).
That's all fine and dandy but what if you want the child process to actually do something? Cause if you stop it or send it in an infinite loop then you can't quite work within the child can you?
That's actually the part i'm interested in: working within the child but prevent it from forking once the parent forks again.
