Journalling protects you very well against you hitting the reset button
or crashing the kernel. In these cases, the disk still has power and
makes sure that the data just written by the kernel hits the platters.
When you pull power, it becomes a race between the CPU, disk electronics
and disk motor. Writes that got to the disk might not make it from the
disk's on-board cache to the platters.
