> Were you earnestly asking that question in good faith Yes, because although I read the whole thread, I didn't get the connection between arenas and the rapidly changing hardware landscape. Now I want to learn more. And, as someone who merely uses Rust in some projects and thinks it's likely to be the least bad alternative for some others, I have no problem contemplating that Rust might have chosen a suboptimal default allocation style.
