* Redefine what an external page isRichard Braun2016-09-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of a "page considered external", which apparently takes into account whether a page is dirty or not, redefine this property to reliably mean "is in an external object".
