## Summary This PR updates Salsa to pull in Ibraheem's multithreading improvements (https://github.com/salsa-rs/salsa/pull/921). ## Performance A small regression for single-threaded benchmarks is expected because papaya is slightly slower than a `Mutex<FxHashMap>` in the uncontested case (~10%). However, this shouldn't matter as much in practice because: 1. Salsa has a fast-path when only using 1 DB instance which is the common case in production. This fast-path is not impacted by the changes but we measure the slow paths in our benchmarks (because we use multiple db instances) 2. Fixing the 10x slowdown for the congested case (multi threading) outweights the downsides of a 10% perf regression for single threaded use cases, especially considering that ty is heavily multi threaded. ## Test Plan `cargo test`
