It's easier to erase it again than prove it's empty. Reading the whole 
thing ten times wasn't sufficient - an improperly erased bit could return a 
zero on the eleventh read, after the whole device was reading 0xFF on the ten 
previous reads.

The erases aren't done synchronously - they're done in the background. They 
shouldn't hold the mount up. I suspect the patch you committed will make it 
start failing Vipin's powerfail tests again.
