NAND Framework in HEAD.

A further issue that flash filesystems take care of is that the nand 
flash erasure block size may not be the same size as the logical 
filesystem sector size (it may be much larger).  In order to update an 
existing block, it may be necessary to read and re-write all of the 
other logical filesystem blocks which share the same erasure block. 
Again, this is something that SSDs already handle internally (since 
they use nand flash).
