- Thank you for your insightful analysis of my understanding of computer I/O.
- You'll have to forgive me, but I'm not altogether sure that you got my point.
- Raw mode is faster because it does less, and some of the less that it does
- (such as newline checking), Waffle needs. If the file system doesn't find
- the newlines, then Waffle has to find them, presumably in a second scan of
- the incoming character stream. I'd be surprised if Waffle could do this
- search as quickly as the file system (which has to count the characters any-
- way) could do it. But as you say, what do I know?

- I don't know Tom personally, but you're the first person I ever heard call
- him lazy or forgetful. I wish all the commercial software that I use were as
- reliable as Waffle.
