As of about two days ago when we sped up the mount by an order of 
magnitude, yes. I haven't yet got round to doing the full check later -- 
easy to do though now we've done the same for all the data and dnode crcs.

Er, the write will fail and we'll panic at the moment. Or at least go into 
an endless loop without skipping over the offending region.

The case I'm worried about is where we get a CLEANMARKER node in the 
_middle_ of an erase block.
