I agree its slow, but what process other than merging really needs to
loop through all documents and read their stored fields? For merging,
having a 64KB buffer around doesn't impact users, because there is
just one thread and its short-lived. Keeping around 64KB ram
per-segment per-thread in general seems too heavy IMO.
