Assume that I've got a read only global section that is paged from
the backing store. I'd like to modify the backing store file and
then force the memory copy to be updated.
One thought is to modify all of the GTE's (global page table entries)
to indicated that the page is not in memory. Will I then have to
updated the PFN's and return all the existing memory to pool?
Are there any clean ways to do this? The reason that I ask is because
I want all the nodes in the cluster to read from the backing store
and then update the file and force all the nodes to re-read the
file.
Any hitches?

Yuck. Sounds like you want to coordinate access to a global section
in a cluster. Try reading note 297, especially 297.3, and see if
that helps.
