If a database engine or another application keeps both the data and the
log in the same filesystem, a snapshot wouldn't create inconsistent data
(I think this would be true with vim and a large number of database 
engines; vim will detect the swap file and datbase should be able to 
detect the inconsistency and rollback and re-apply the log file.)
