Adding a max runtime timeout to Deno JS execution

As the title states, I would like to be able to add a timeout to any JS code that I am executing in my deno_core JsRuntime in rust. I haven't been able to find any way to get this to work as all solutions seem to require that Deno yields the async runtime which it doesn't ever seem to do until it finishes. Any advice you could give or places you could point to would be extremely helpful, thanks!
