IMO, it would be more interesting to see it done top-down, instead of bottom-up. That is, instead of starting with rewriting `strlen`, why not start with rewriting `getaddrinfo`? That would be a very interesting project because you could write `getaddrinfo` with a safe Rust API (i.e. one that doesn't require using `unsafe` to call it), and then wrap it in an `unsafe` function that exports the unsafe C `getaddrinfo` function. This could arguably then be an improvement on the musl code.
