Randall Stewart be27fdd0c4 LOR fix - Lock only when calling the actual code that
is messing with the UDP tunnel. This means
          that if two users actually tried to change the
          tunnel port at the same time interesting things COULD
          result, but its probably very unlikely to happen :-)
