I need to use SIG{CHLD} in this case - the parent accepts connections, if there is no child running, it starts a child to service the new connection. If there is an existing child, it tells the new client it can't connect as it is in use from ip:port. The child can exit nonzero - when this happens, the parent needs to exit immediately (not at the next accept().

So the parent needs to detect new connections, and a child exiting. The issue I'm concerned with is more general - If I'm using signals anywhere (eg sleep()), do I need to wrap every system call in a loop to retry it??
