Thanks Shawn. That's a very helpful and clear explanation.
I'm still a bit puzzled, though. Do you know how other 32-bit apps
handle long vectors? For example, sound or video editing tools that
can be used to edit long (hour-long, multi-tracked, multi-GB-sized)
chunks of data? Are they just paging small chunks of data to and from
the hard disk?
