In rebuilds, 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.

This only applies to rebuilds, as a way to avoid breaking the
templatebody plugin, unlike the earlier version of this optimization.
