Applied. Except instead of hunting down the NAE I stuck with the try/catch
but put it outside the while loop. The key is that the catch block will
call tryClose(). That will setup the client to reestablish the datagram
socket with subsequent requests. So if anything goes wrong (not just NAE)
it will log the exception and close the datagram socket so the client will
start fresh.
