Precisely my thinking! try to avoid concurrency as much as possible and if you _really_ have to use it, try a queue approach.

It adds lots of complication that often isn’t necessary. Where you do need it, queue results or commands and then have workers to process those - workers, queues and commands put you back into easily testable territory. Then you are left with the concurrent bit - hopefully now quite tiny and specific, which you you can normally blast and test if you have concurrency hole - but in the realms of can it queue things up in an orderly fashion and dequeue them as well. Deep code inspection on this is also helpful (albeit manual).
