It _looks_ like you can use Wasmtime across threads in a similar way to browsers:
- Create
wasmtime_sharedmemory_t *- Create one store/instance per thread, with this shared memory as an import
However, some documentation would be extremely reassuring here.
Feature
Documentation and/or example code for how multiple (host) threads can make simultaneous C API calls which affect the same shared memory.
Benefit
Makes it clear that Wasmtime supports this use-case

Yes it's the same model currently, creating/sharing memory and instantiating once-per-thread. There is not currently documentation for this and you're correct it'd be good to add some!

I'm going to close this as I think it's answered, but feel free to follow up here if there's anything else.

Looking for the same information. Can not find any practical example that demonstrates this feature for any language.
