Error when removing an event while it is being triggered

[aaronholsonege]

An error occurs when calling EventBus.off for an event that is currently firing. The following example will throw an error:

var callback1 = function() {
    EventBus.off('test', callback1);
    // ...
};
var callback2 = function() {
    // ...
};
EventBus
    .on('test', callback1)
    .on('test', callback2)
    .trigger('test');

This is happening because the event stack array is being modified while it is being looped through.
