## Performance Improvements

- **md:** join a leaf's lines by slicing the source into the arena, and scan it for NUL once ([4b02d10](https://github.com/datisthq/textlane/commit/4b02d1000774c2847fb833606093c8746ebf7e5c))
- **python:** release the GIL while process runs, and run aprocess on a thread ([250ca06](https://github.com/datisthq/textlane/commit/250ca067360fbbc8ffebf9225632b24a9b996aa7))
- **typescript:** hand process's result to Node.js as a typed object, not a JSON value ([17b1321](https://github.com/datisthq/textlane/commit/17b1321dab9584f7dc976f2a3370e4a475f353e7))
- **typescript:** run process on worker threads, with Oniguruma compiling regexes in parallel ([5355947](https://github.com/datisthq/textlane/commit/53559474e369b8327650baa8979841fad4f32ba9))
