True :)

I'm not sure it would help in the case where the cleanmarker says a smaller 
erase size than the hardware. I think we should just stuck 'probably' empty 
blocks on a separate list and finish scanning them before actually starting 
to use them.

Not always. It's usually been safe to make a JFFS2 image with erase size 
smaller than the hardware, so people making images for the iPAQ, for 
example, will build images with 0x20000 erase size to match the H3100 in 
the knowledge that it'll work OK on the H3600 and others.
