There's probably a reason why you want to process that file - splitting it can
be a problem if you need to keep track of some states and it splits on the
wrong line. So, I'd probably open it in perl (or whatever processor) directly
and use a database for storage if I really need to keep string contexts, so
that on each line iteration my perl memory is clean.
