Are you suggesting that long boots after system failure is the option?
I think journaling for larger databases is mandatory. And advisable for
any other case.
If there are issues with our fsync(), we ought to fix them. And perhaps
invest some time in optimisations, like Oracle invested time to decrease
fsync() latency on ext3, recently.
