Problem with async mongodb driver

According to the documentation: Dropping future returns by the async mongodb driver may cause the driver to be in an inconsistent state internally, which may lead to unknown behaviors.

They suggest creating a separate task to ensure that future returns from the driver will be completed, e.g.

let collection = client.database("ok").collection("ok");
let handle = tokio::task::spawn(async move {
    collection.insert_one(doc! { "x": 1 }, None).await
});

On my server, the request is dropped when the client disconnects for various reasons.
I don't want to spawn new task for every database operation.

Can you simply disable the timeout?
