Illustrator Scripting :: CS5 - Clean Way To Unlock Endless Sublayers?

I've written a snippet that will unlock sub of sub layers up to 10 layers deep. It works fine; however I'm wondering if there is a better way to do this? I don't know that 10 is the maximum of sub layers I'll need to unlock but it's a fairly safe guess. I'd like to be more efficient and know that no matter what the layer structure of the file my script has unlocked any and all sublayers.
 
Is there a different approach or way to think about this problem where you can script for a potentially endless number of sublayers, and subs of subs, etc.?

var layerCount = doc.layers.length;
for (i=0; i<layerCount; i++) {
var currentLayerI = doc.layers[i];
var layerCountII = currentLayerI.layers.length;
for (ii=0; ii<layerCountII; ii++) {
