The "New York version" (hunchentoot:start (make-instance 'hunchentoot:acceptor :port 4242))

creates a stalling web server, never loading, never error'ing.

When I remove the code :ready-only t from line 377:

(when (usocket:wait-for-input listener :timeout +new-connection-wait-time+)

The New York version works fine.
