DISREGARD, I realized I had booted into Linux to copy my Music (13GB) to my
external hard drive (USB-C enclosure for my NVME 512GB SSD).  As I was doing
so, I saw free RAM falling and then fired up vmstat again.  Swap usage climbed
(literally only used Yast and Chrome after a reboot).  Check the second set of
vmstat logs after the time delay.

Sorry about that, I spoke too soon.
