Hello! Was curious about the threads proposal. I was wondering if it is something still planned, I am writing a small toy async preview 2 runtime https://github.com/StaticallyTypedAnxiety/tiny-async-runtime
I think its gotten to the point where I can see it working with threads. I was mainly wondering if threads is something that will come with preview 3 down the line?
Hey @Ashanti Mutinta have you seen the new sections in the Canonical ABI on this?
Design work is still on-going but IIRC @Andrew Brown is the right person to update you here

Oh perfect! I read the streams and future parts but havent read the spawn yet. I shall take a look. Thank you!
You may also benefit from the PRs that lead to that: https://github.com/WebAssembly/component-model/pulls?q=is%3Apr+thread+is%3Aclosed
Lots to dig into there!
@Ashanti Mutinta I can answer any additional questions you may have; we definitely could use more help pushing that proposal forward.

Awesome thank you. Is there an experimental target we can play with by any chance? That is probably asking a bit too much but i was curious :sweat_smile:
I suppose once the proposal has moved forward a bit, it would help those producing Wasm from LLVM if there was a LLVM instruction.
Yeah, no target yet.
