Please forgive me for the stupid question.  Would Ryan's concerns be
addressed by configuring ext4 to run in data=journal mode?

I realize that as a programmer he cannot guarantee that his application
will run on a file system in a particular configuration.  I'm just
curious as to how this all fits together.
