Hi team, I wonder if calling into WASI reactor module is thread safe?

I'm running tokio in WASM and in a separate native thread I want to call into my WASI module function which would call waker and wake up(add to the async runtime queue) a Future

The static return area generated by wit-bindgen isn't thread safe. Other parts might be, but for now this is considered unsupported below WASI 0.3.
