   Once we get reverse-journaling (UNDO records) working, we can do it
   the other way.. the mirror would contain the completely up to date
   filesystem and the journal files would be used to 'revert' it to an
   earlier state if necessary.  This is safer because you can run the
   filesystem closer to 100% full (when it fills up you just remove the
   oldest journaling file), and you can restore a backup from the live
   mirror without having to run through any journaling files.


excellent work! great stuff!
