Ok, good.

That should have the speedups I was referring to.  Basically checking
the node CRCs is deferred until after mount time so the mount succeeds
much more quickly.

There is one more feature pending that I know of.  Ferenc Havasi has
some eraseblock summary changes that should help.  I believe the
intention was to commit that to JFFS3, but I haven't seen it go in yet.
