This is only used to potentially defer the processing of requests (ie, in the
case that the prerender causes a prerender). These URLs should already be in the
prerender tracker if they are in the other prerender contents. You shouldn't
need to add them again.

If you do want to add them here, please make sure they're removed correctly as
it could cause some subtle bugs where requests are delayed.

Good catch!  I thought prerender trackers were on a per PC basis, but its a
global one.  So I agree with you and I removed this.
