What's the coroutine status? If my response needs to call a suspend fun, should I just runBlocking {} ? What's everyone doing there?

as per @dmcg's videos around this, I think the sensible answer is to use a loom dispatcher and run it like so (if you're using a loom-enabled VM 🙂. ):

val loomDispatcher = Executors.newVirtualThreadPerTaskExecutor().asCoroutineDispatcher()

fun <T, R> (suspend (T) -> R).runningOn(
    dispatcher: CoroutineDispatcher
): (T) -> R = {
    runBlocking(dispatcher) {
        this@runningOn(it)
    }
}

I think that it the first place I played with newVirtualThreadPerTaskExecutor. You might need
