Hardly "big" by the OP's standards at only 4.5 MB (and roughly 790,000 
words, if anyone's interested).

The problem with processing terabytes is frequently the need to 
accomodate the data with techniques that allow the virtual memory to 
avoid becoming swamped. The last thing you need to do under such 
circumstances is create an in-memory copy of hte entire data set, since 
on most real computers this will inflict swapping behavior.
