Not really. Userland data are flushed to the medium on fsync() or sync()
just as with other file systems. If a write() call has _just finished
when the power is lost, there's no guarantee that _any_ file system will
have committed that write to the medium already. (Unless you were using
O_SYNC, which we don't support for JFFS2).
