@RobertLowe that was my first thought (#call), because I can clearly see the benefit of calling this method #call, as I believe that there will be enough apps that will just utilize the ThreadedConsumer, if a more robust queueing is not required. I currently have a very similar home-made approach for performing some OOB http requests, which enqueues lambdas. The very low traffic profile makes a fully-fledged queueing solution a sure overkill in this case.
