When a TCP client opens multiple connections beyond the server's
backlog capacity, the call to connect() returns a value of zero
(success) after 9 seconds. Toggling SYN-cookies makes no difference.

Is this intended behaviour?

Under Solaris I get ETIMEDOUT (Connection timed out) after a little
less than 4 minutes.

Presumably I could set the socket to non-blocking and select() for
writability... (I have not tested that yet.)

But if I want to keep it simple, what is the recommended solution?
