These logs were produced  as follows:

Server A comes up first and stays up the whole time.  B comes up with
the wrong credentials and, the first time, gets the join rejection/auth
failure message from A and throws the SecurityException on its side.  I
ctrl-c kill B.  Then start B again and it falls into the join timeout
loop.  Ctrl-C will no longer stop the process so I have to kill -9 it.
Finally I start B one more time - this time with the correct credentials
and it ends up in a similar join timeout loop.

> When AUTH processes a JOIN request and rejects it, it sends back a unicast message to the joiner. However, that message is dropped by UNICAST as the destination is not in the membership !
> SOLUTION: use Event.ENABLE_UNICASTS_TO before sending the rejection. (This works in TCP as there is no UNICASR protocol in TCP)
