Dima,

You're connecting to the server using HTTP, so the server should  
return valid HTTP header, i.e.:

     class TimeServer < GServer
       def initialize(port=10001, *args)
         super(port, *args)
       end
       def serve(io)
         str = "HTTP/1.0 200 OK\r\n\r\n#{Time.now.to_i}"
         puts str
         io.puts(str)
       end
     end

Haven't tried it on Windows, but this works on Mac whereas your  
version fails as you described.

Best,
Mike Dvorkin
