Mike,
This doesn't help. Before, eventually looking into the source of 
gserver.rb I tried my code on Debian Linux - same error. Which is good, 
at least Ruby is consistent accross platforms.
If you look at gserver.rb you will see that this server closes client 
socket right after it servers it, which he must not do and which 
perfectly explains why gserver.rb does not work correctly.
Also see my coments (#dk:) inline:

gserver.rb closes client socket right after serving it :(
From gserver.rb:

          client = @tcpServer.accept
          @connections << Thread.new(client)  { |myClient|
            begin
              myPort = myClient.peeraddr[1]
              serve(myClient) if !@audit or connecting(myClient)
            rescue => detail
              error(detail) if @debug
            ensure
              begin
                myClient.close
              rescue
              end
              @connectionsMutex.synchronize {
                @connections.delete(Thread.current)
                @connectionsCV.signal
              }
              disconnecting(myPort) if @audit
            end
          }
        end
