For my own purposes (speed at any cost), "to hell with doing it 'right',
just DO it'" instructions to the caching mechanism would be fine.

Half the time I am just backing up THROUGH something, not even reading
(via my eyes) anything on the page, just backing up to the prior one.

I DON'T CARE whether that page is in-sync or not.  If I worry 
about a given page, I can just do a ^C, and get a "fresher" copy.
