    // The $nids array will be broken into smaller chunks.

        // If these nodes existed in the system prior to this page request, there is a chance

        // Only PuSH the feed if there is actual data.  The view may have filtered
        // our nids down to 0, in which case we don't want to send anything. Because
        // normal View requests (Pull-based) are unaffected, Atom subscriptions still
        // work as normal.
