it doesn't need to check if the journal is valid, it just replays the
journal. if you crash and the journal is not valid, it will check and
repair if necessary.

The ability to do a "live repartition" of a drive in Disk Utility
requires journaling. The same mechanism is used by Boot Camp Setup
Assistant, so journaling must be turned on when you first set up Boot
Camp, or before you remove it.

Time Machine also requires journaling to be enabled on its drive.
