Hmm. Out of interest, What happens if you apply this? Again, profile data 
are useful :)

DO NOT LEAVE THIS IN. It disables the CRC32 check on nodes during mount. 
It's the first (and easy) part of the proof-of-concept which involves 
moving said CRC32 check to later so the mount doesn't have to wait for it.
