The fact that listeners are fired in some order, and that the new custom one was automatically (it seems) added to the end, makes one ask, "What determines the order?" and "How do I alter that if desired/needed?"

Yo Michael!

You've been curious lately - awesome :). So there *is* a priority attached to each listener - from -1024 to 1024 irrc, and a new listener defaults to zero. Most of the time, you don't care when you're called, but in a few cases, you do (e.g. maybe you want a listener to be called *before* routing, which has a priority of something like 32). In that case, you can add a "priority: 100" and you're all set!

Cheers!
