If we create separate listening sockets in each worker using SO_REUSEADDR, then an incoming connection may be load-balanced to a process that is already busy, either due to a long-running request, or because it is a recursive request (in which case we would deadlock). Instead, only create one listening socket, and only create worker forks afterwards. This way the incoming request will be served by one of the workers that is currently listening for an incoming connection.
