Root LFS filesystem that had been filled with an unlinked file (dd
=2E.. of=3Dfoo &; rm foo) and then crashed deliberately when the dd
process seemed to get stuck exiting when it filled.

After the reboot and automatic fsck -p, in the first instance, the
cleaner wasn't making forward progress, and wasn't recovering the
space.  I shut the domain down again and forced a full fsck.  This
found the unlinked file and cleaned it up - but left damage of its
own. A second run fixed that.

After a reboot and mount, the fs is still 107% full.. but the cleaner
seems to be slowly trickling the space back.
