Thread of execution depends on event's listeners.

[Elergy]

If we have a few of subscribers and one of those throws an exception, our thread of execution well be interrupted.

For example:

var hub = new Mediator();
hub.on('test', function func1() { console.log(1); });
hub.on('test', function func2() { throw new Error('test error'); });
hub.on('test', function func3() { console.log(3); });

hub.trigger('test');
console.log(4);

Actual result:

1
throwing exception

Expected result:

1
3
4
and throwing exception with stacktrace
