Booted back to 4.10.0-37-generic and the problem seems to have gone away. This was 2 kernels ago. I will try -38, the intermediate version, and report back.

The behavior is that the trackpoint begins behaving as if one is holding the middle trackpad button - instead of trackpoint inputs causing expected mouse pointer movement, windows switch, windows scroll. I've seen erratic pasting as well. Once entered into this mode, the only way to return to normal is to left or right click - in the trackpad (left click on the buttons above the trackpad don't help). Then you are safe for the next 15-20 seconds until another faux-middle button press happens. This behavior is totally new with an update sometime in the last 2-3 weeks (I don't often reboot).
