Note that if you're on an IDE drive and you haven't disabled the write
cache, you may as well turn off fsync as well, as it's just getting in the
way and doing nothing, i.e. the IDE drives are already lying about fsync
so why bother.
Step the first, get on SCSI / or a good IDE RAID controller, then step the
second, turn fsync back on. Without reliable storage, fsync is a dunsel.
