> The lazyio package is not what people are talking about when they say "lazy IO".
I don't know which people you are talking about, but it clearly was in this specific subthread which started with a complaint about “LazyIO”, not “lazy IO”, and where the only use of “lazy IO” in a post before yours was in a post where all previous references were to “lazyIO” and it's specific package documentation, and contextually the “lazy IO” references was about the same thing, not something else.
