OK, so how would you size the block size based on the file size? That's
the part that isn't quite clear to me. There could be a number of valid
options in that area, and things like buffered/unbuffered IO might
influence that as well. In other words, it would involve some
heuristics, which I'm never that crazy about adding.
But tell me what you are proposing in detail, and we can take it from
there :-)
