The parking_lot crate is a Rust port of WebKit’s original WTF::Lock — this 2024 changeset shows how eventual fairness was implemented there. You should read it, it has very good performance insights on mutex contention. Think of it as a palate cleanser from this blog post. Now back to the hash table & the lock.
