That's because the default buffering mode for stdout is #f (no  
buffering).  For tcp ports the default buffering is #t (fully  
buffered).  You can change it like this:

(open-tcp-server
   (list port-number: 22222
         buffering: 'line))

to get "line buffering", or use #f for no buffering (this may be  
really slow as each character is sent individually).
