Post #1248881

I also built `ft-review-toolkit` (using ThreadSanitizer) to check for free-threading readiness, which has found real data races in 12 extensions so far. If you maintain a Python C extension and want a high-quality, human-reviewed bug report (or help migrating to free-threading), just let me know! All the toolkits are open source: https://github.com/devdanzin/cext-review-toolkit https://github.com/devdanzin/ft-review-toolkit #Python #CPython
