Does this imply that on-disk inodes that are not initialized yet might
have non-0 block pointers? If so, does it further mean that we do not check for
(inode I is used) being consistent with (its block pointers are 0)
anymore? If so it would be nice for unlink() not to reset block pointers
to 0 when then final reference to a file is deleted: that would allow
resuscitation of deleted files.
