Yes, the same thing with regards to arrays using an extra level of indirection
is still happening with 20051202. If I have an array with elements of type
{ key: Word.word, ord: int }
then it uses 16 bytes per element. That must be 4 for the pointer in the
array and 12 (2 4-byte fields and one 4-byte header) for the tuple/record
being pointed to.
