Server is multithreaded, but no connection is visible

Browse Source 
UDPNetworkUtility and ConfigUtility are now using the ServiceLocator
pattern in the server, and networkQueue() is running in a separate thread
in the server. However, there seems to be a problem somewhere, since the
broadcast request & response are not producing any visible output.
