Offhand, I'm not sure (Todd probably has a much better quick answer
for this question than I do). It is perhaps something that would
allow us to test 64-bit arrays before the Python changes are
ready if it isn't too hard to optionally disable the dependence
on Python sequences. It's worth a quick look at after 1.2 is released.

Just to note, we more and more local users who are begining to
have a need for such large arrays too.
