[3.8] bpo-38778: Document that os.fork is not allowed in subinterpreters (GH-17123) by miss-islington · Pull Request #17179 · python/cpython

Small docs update for bpo-34651.

Other references to fork (e.g. the PyOS.*Fork functions or discussions of fork() when embedding Python) point back to os.fork, so I don't think any other updates are needed.
