Dag-Erling Smørgrav b6924c9309 Add a toggle to display the approximate amount of swap used by each
process.  We don't *quite* pull that number out of our backside, as
the actual number is difficult to determine without modifying the VM
system to report it, but it's still useful to get an idea of what's
going on when a machine unexpectedly starts swapping.
