Did you notice 3a?  Double-page-write allows you to write to pages
more than once.

Plus, there is the long-term solution as well.  Jffs2 can write the
information anywhere, not just into the same physical eraseblock.  For
logfs, I will store that information in a special file.  JFFS2 doesn't
even need a special file but can introduce a new node type.  Basically
an erase marker for a _different_ erase block, with some versioning to
make sure it doesn't get deleted (through GC) before the erased block
is used.
