Matthew F. Dennis commented on CASSANDRA-1160:
----------------------------------------------
just FYI, if Gossiper.start() is moved before MessageService.listen() the unit
tests show sporadic (~ 1 in 5) errors even though the tests still pass.

> Gossiper.start needs to be integrated into the constructor. Currently you
