Speculative swap-in?

On an otherwise idle system with large amounts of free or cache-only
pages it might be useful if the kernel would speculatively load some of
the swapped pages back into memory. It should leave them in swap too in
case the memory is needed again (much faster to just throw it out than to
write it to disk). This would help restore the system to its previous
state after backups well before the person gets back to their computer.
