Not for very large files: the forget-behind is absolutely critical in

I dunno why you're thinking of unmapping pages though...  But you do
want them to be dropped from memory when appropriate.

We want to *physically* unmap them from the page tables.  You can't
evict the pages from cache if they are still physically mapped!
