It seems that the 'syncft' option was labeled poorly, then. That's
specifically the double in-memory checkpoint/restart fault tolerance
mechanism. The other mechanism, 'mlogft', is based on message logging.
Either one of syncft or mlogft enables fault tolerance support, but
only one mechanism or the other can work at a time.
