How about this case:
Growing file starts in chunk A.
Overflows into chunk B.
Delete file in chunk A.
Growing file overflows chunk B and spots new free space in
chunk A (and nothing anywhere else)
Overflows into chunk A
Delete file in chunk B.
Overflow into chunk B again.
Maybe this is not realistic, but in the absence of a mechanism to pull
data back from an overflow chunk, it seems at least a theoretical
possibility that there could be > 1 continuation inodes per file per
chunk.
