JS - nice sleep-alike functionality

I have a very CPU-intensive JS function that makes browsers kill it because of long no response. I want to have the function finished, and also i want to be able to use my browser in the meanwhile.

My solution was to implement a sleep-alike functionality in my function after each iteration:

<p id="debug"/>
<script>
    function example(i) {
            //do stuff
            if(i < 100) window.setTimeout(function() {example(i+1);}, 100);
    }

    example(0);
</script>

The solution works well - but is there is any nicer way to implement this functionality? - without using the unnecessary recursion.

var sleep = function(period, decision, callback){
    var interval = setInterval(function(){
        if (decision()) {
            interval = clearInterval(interval);
            callback();
        }
    }, period);
}

There is something called web workers which is similar to Threading. Refer: http://www.html5rocks.com/en/tutorials/workers/basics/
