This of course is even *WORSE* than using sequential_io, since
there is extra positioning overhead. I can't imagine why you
would choose Direct_IO for what is obviously a sequential
problem. Just shows that if there is a way to abuse things
someone will take advantage of it :-) :-)
Yes, of course, using Stream_IO in big chunks is the only
sensible implementation approach.
