CCL 1.11’s make-udp-socket function will call "%socket-connect” if keyword arguments remote-host and remote-port are provided with make-socket. This is new in CCL 1.11:
(defun make-udp-socket (&rest keys &key (fd -1) (connect :active) (address-family :internet) remote-host remote-port &allow-other-keys) (unwind-protect (let (socket) (when (< fd 0) (setq fd (socket-call nil "socket" (c_socket (ecase address-family (:internet #$PF_INET) (:internet6 #$PF_INET6)) #$SOCK_DGRAM #$IPPROTO_UDP)))) (setq socket (make-instance 'udp-socket :device fd :keys keys)) (apply #'set-socket-options socket keys) (when (and (eql connect :active) remote-host remote-port) (%socket-connect fd (apply #'resolve-address :host remote-host :port remote-port :allow-other-keys t keys) nil)) (setq fd -1) socket) (unless (< fd 0) (fd-close fd))))

usocket from the current quicklisp dist is calling (ccl::inet-connect ...) with a few parameters it gets by calling other unexported CCL functions.
Just this line is sufficient to get to the (first?) problem:
(usocket:socket-connect "localhost" 1111 :protocol ':datagram)
In a quick glance around trunk, I didn't see where make-udp-socket would invoke connect(2) or any way to do it after-the-fact.

I can try to look at it. What version of usocket are you using? Is there a place I can get it easily so I can try to run your test case and duplicate the problem?

It gets an error:
