This way we can properly benefit from native parser in parallel type checking. Self-check is now ~2.2x faster with 5 workers compared to in-process checking (also with native parser). Also it uses less memory, but still with 5 workers, self-check takes ~twice more memory compared to in-process.
Implementation is mostly straightforward. The GC freeze hack needed some tuning, as there is no single hot-spot in terms of allocations anymore.
Note: do not use
maturin developfor any performance measurements, as this creates some very slow wheel.
