Subject: [PATCH] Assume that every page has been scanned by the time the scan
phase ends
This doesn't prevent memory from being used to track what we have
and haven't scanned, but it does make it temporary. The existing
%rendered hash, which is filled afterwards, will be larger than %scanned
in practice anyway: %scanned will contain an entry for each page
that changed, plus an entry for each template used by templatebody,
whereas %rendered will contain an entry for each page that changed
plus an entry for each page rendered due to links or dependencies.
