It could. Indeed, I believe there are people who sell boxes full of
slowish RAM chips as fast disks (this could also be useful for paging
on a machine which can't have more main memory added). You might well
want to avoid the waste of having blocks from the RAM disk duplicated
in the buffer cache, however.
