issue9035.2.patch is an updated version of Atsuo's patch. 

Known issues:

* I haven't reworked it for the new memory-management API
* There's no test for a non-root mount point (which is really the basis for this issue). It's difficult to see how to do that in a robust way on an arbitrary machine without quite a bit of support machinery. I've done ad hoc tests which succeed.
