Along that line, can hot standby rabbits be made by rsync'ing the
/var/lib/rabbitmw/mnesia directory to another machine?  To rephrase
the question, is the data on disk always valid, or at least
recoverable?  Obviously any work done between the snapshot and the
machine failure would be lost, but would the on-disk data be usable?
