The idea is that the FIFO absorbs sequential scans and filters out the

do we consider it for longer-term cacheing.
Page aging does that. The initial age of a page will be fairly low,
relative to pages which are constantly being accessed, and so will
be evicted from the cache before they can accumulate a high age if we
have a sequential access pattern.
