Normal filesystems on mtdblock are always going to be horridly
unreliable. If you lose power at the wrong point during the
read/modify/erase/writeback cycle you've lost a _lot_ of data, not just
the sector the file system thought it was writing.
I don't care much, but if you see a way to make sync() have the desired
effect I wouldn't be averse to it. Criticism in 'diff -u' form always
preferred :)
