That's a much better justification for Rust's impl over glibc's. Given the comment this tree sprouted from, the argument seemed to be "Rust is memory safe and uses futex-es", which was pretty weak. I see the benefit of Rust here as being a kindof modern refresh of the building block concepts, which have calcified in standard C. With Rust, the refresh is now in std, or in a popular crate (where it is accessible via package managers). Alternative C standard libraries are hampered by having to implement awful parts (like locales, the string routines), and while C has an even greater quantity of excellent alternatives for smaller slices of "std" functionality (both open and closed source/in-house), discovery is less good. I'm not sold on every aspect of package managers, but I can't deny they have made some difficult things easy.
