Indeed strace doesn't lie but you have yet to provide an example of a system where what you're saying about cat is true. You've shown a number of examples which do not actually back up the claim you are making, and have not responded to other posters pointing out the flaws in the examples you did provide.

I'm genuinely curious to see an implementation but I suspect you've misunderstood something in the past and your statement was incorrect.
