shouldn't this be async so you can avoid blocking?

Async in Wit is just a hint, so you can avoid blocking either way, and the main question is what the default should be.
In my experience most programs that use stdin use it in a synchronous way, which suggests making it sync by default, but I don't have a strong opinion about it.

many C programs use functions like kbhit or O_NONBLOCK on stdin, imo we should have support in the C library for stuff like that, afaict that requires the C library to use the async version even if most programs just block.

Thank you for contributing to WASI! As part of our proposal management process, we decided to consolidate all phase 3 proposals into a single monorepo at WebAssembly/wasi to better manage the proposals that have reached phase 3. We have completed migrating all phase 3 proposals to WebAssembly/wasi including their issues, but PRs need to be re-opened in the new repository. This is a GitHub limitation and we're sorry for the inconvenience. Please re-open this PR on WebAssembly/wasi. Thank you! |

There are still some FIXME comments in the code to resolve.
