That's a clever technique.  It only works so long as the journal
blocks haven't been reused, so you would need to use your tool very
*quickly* after the files had been deleted.  If the inode table block
hadn't been modified before the deletion, it might also not appear in
the journal, so it's also not guaranteed to work.  But certainly it's
a better shot than no chance at all.....
