It means fleeting, not > persistent and I think we have not used that term with a page/folio yet. I also hit the thesaurus ;-) I'm honestly not too worried about the internal name, as developers can figure that out. It's more about presenting an external name that sys developers will not need a lot of explaining to know what it's about. And something that isn't too long. BRIEFLY_CACHED? TRANSIENT_CACHE? Dunno, I keep going back to uncached as it's pretty easy to grok! -- Jens Axboe
