Subject: [CR]Cracks!

I found a couple suspicious-looking meandering cracks on one of my Zeus crank arms. These are not like the cracks I've seen on failed cranks, and appear to be quite superficial, perhaps only involving the anodized layer:

Anybody have anything to share on the significance of such cracks?
