And if it's actually doing a copy, then it's also a speed-damaging language misfeature.

It might not be much, but papercuts add up.

Dunno how they'll fix it but it needs fixing ...

For what it's worth as a Rust user, these Rust for Linux issues seem to be becoming a very helpful forcing function to improve Rust itself.
