the crux of it is

await

- in the end you are still waiting for all the code to complete, so

async

doesn't buy you anything unless you have a process that truly has steps that can be done in parallel without any dependency between them. So Darren, it sounds like you're thinking you might have some

async

methods without

await

? such that async things get processed in the background? Per Eric's point - that's exactly what Scheduled/MR scripts are for and they have a well defined execution model (with timeouts, governance, etc).
