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.
