Should work at least as well with ZFS.
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.)
