 Maybe.  I had the impression that, after a crash, files would usually be
 missing, or moved to lost+found, or still containing old content (or a
 mixture of old and new content).

 If what you mean is "there are known bugs in this area", OK; but if you
 mean "crashing is not a bug" then I disagree.  I expect the file system
 to be left in a bad state if the machine crashes for some reason (due to
 hardware failure or a kernel bug), but I do not expect the mere usage
 of ffs-async to cause the machine to crash.
