Actually chunk size is not read because there is no code to try to read it.
The chunk size needs to be reported by the personality, and they are
inconsistent in the way they report it so it is much easier to just ignore it.
GET_ARRAY_INFO gets the chunk size easily, so we stick with that when chunk
size is needed.
