Which language? Usually there's a thread pool where multiple tasks are run in parallel. CPython is a special case due to gil, but we have pypy which has actual parallelism
I've only ever used it in those lua microcontrollers and in Rust with the async keyword.
In lua I doubt they use proper threading due to the GIL. Rust probably can do async with threads, but it just wasn't fun to work with.
Tokio has support for multiple threaded async in rust.
As for micro controller, I don't think you can have multiple threads in flight anyways, so that's the best you'll get
