The architecture of this system should separate the iteration across the I/O 
from the transformation *on* the data.   It should also allow the ability to 
plug-in different transformations at a low-level --- some thought should go 
into the API of the low-level transformation.    Being able to memory-map text 
files would also be a bonus (but this would require some kind of index to allow 
seeking through the file).    

I have some ideas in this direction, but don't have the time to write them up 
just yet.
