True. Without the ability to brutally cut the power to a cloud
instance or other remote (and in some cases possibly virtualized)
server, it's practically impossible to test that. We're basically
relying on replication and hoping that three instances (master and two
slaves) don't go down simultaneously, which is hardly a guarantee.
