JFFS2 needs to scan through *all* write nodes upon mount.
Imagine what happens when you have a giga/terrabyte flash
where you write millions/billions of tiny log entries..... it would
take *forever* to boot.
Also memory consumption is proportional to the # of write
operations so that's another trainwrecker.
