There's a more general problem with VM on laptops which is that the system
doesn't have any notion of spun-down disks. Flush intervals should be
short when the disk is running and long when it isn't and decisions about
which pages to discard or swap might be improvable. Pre-emptive swap when
the disk is spun down is a loss..
