For those who need a queue for different reasons ;)

jquery.queue.js

// Initializations.
var theQueue = $({});
var elements = [1, 2, 3, 4, 5, 6];

// Loop through all elements and add a function to the stack for every element.
$.each(elements, function(index, item) 
{
    theQueue.queue('stack', function(next) 
    {
        // Do some processing here..
        console.log('item: ' + item);

        setTimeout(function() { next(); }, 1000);
    });
});

// Executes every function within the stack after excactly one second.
theQueue.dequeue('stack');
