BigString (reducing peak memory)

[Gordon Tyler]

This is just a wild idea, but would using Python generator expressions
help with keeping only a small part of a large data file in memory? If you
only ever need to deal with a non-random-access stream of bytes, then a
custom generator could read data from the file in chunks as bytes are
requested. It would have the advantage of not having to make code aware of
the fact that the data is being chunked.
