-------------------------------------
Dennis, your patch is not using the variable curNodeDepth at all. I guess you
can remove that.
(btw, after the change to use a stack, we no longer get an OOM or StackOverFlow
no matter the depth of tag-nesting, right?)

> Some webpages have a form of a spider trap that causes a
> StackOverflowException in DomContentUtils by having nested tags with
> thousands of layers deep. DomContentUtils when trying to get outlinks uses a
> recursive method to parse the html. With this type of nesting it errors out.
