I'm not sure our backlog can provide what he wants. From reading his mails, he
wants to limit a listening port to allow only 1 connection at a time, thus
denying new connections until the first one is closed.
However, our backlog implementation limits the accept queue, thus allowing
unlimited simultaneous connections if the application accepts them fast enough.
He would thus end up with 1 active connection and 1 connection queued in the
accept-queue.
I'm not too familiar with other OSes, but I think we're pretty much standard
here?
