Javascript settimeout on recursive function?

Question

function theFunction(a){
    var newNum = a+1;
    var iframe = document.createElement("iframe");
    var currURL = urlArray[a];
    iframe.src = currURL;
    iframe.frameBorder = "0";
    iframe.height = "0";
    iframe.width = "0";

iframe.onload = function(){
    document.getElementById('number').innerHTML = a;
};
    var arrayLength = someArray.length;

    if(a != arrayLength){
     theFunction(newNum);
     }
}

This is my basic function that is recursive through an array. Anyways, sometimes as it goes through (during the //do nothing part). It will get stuck, and I want it to timeout after say 2 seconds AND move onto the next one. Is this possible to do, or will I just have to completely stop the function?

EDIT: Set timeout might not be what I am looking for, but some way to just stop the function and move to the next one.

EDIT 2: Added more to the code

Hmmm. Do you know exactly what's happening when it get "stuck"? Because if "stuck" means hitting a loop or some other error then setTimeout won't help you. In my experience, code set to execute with setTimeout will happen when the given delay has passed or when other code has stopped executing, whichever happens LAST. In other words, I don't think you can interrupt currently running code with a setTimeout, which seems to be what you're asking.

I know that's sort of a non-answer; I suggest nailing down the nature of the stuckness instead.
