There was a reason for the cleanmarker -- it saved us from using
partly-erased blocks for data. Do you have some other way to guarantee
that this won't happen?

(Sorry, I think we may have had this discussion before, but I've
forgotten the conclusion, if there was one. It was academic at the time,
since we didn't have any solution for the paired-page insanity anyway. I
was mostly just burying my head in the sand and hoping this stupid 'MLC'
crap would go away.)
