I think there exists a midway, where you rely on the heavily-tested open source solution that implements what you want, and a sprinkle more. RabbitMQ for example is that layer that your 40 lines of code would do, but pays off dividends in good nights' sleep.

RabbitMQ is not free. You need to learn it, configure it, understand it, interface towards it, install it, upgrade it. Lots and lots of things.
