Perfect thanks!

So I ran xev from a Linux console (first: export DISPLAY=:0) and from
another Linux console (two GNU screen sessions in one Linux console
actually, so I could detach, and reattach in X later, to cut and paste
into this email):
$ xscreensaver-command -lock
xscreensaver-command: activating and locking.

Here is the xev output in response to the screensaver locking
(ie in response to running xscreensaver-command -lock):

$ xev -root

and here is the remaining output, a short while later (may be 10
seconds), just staying in the linux console running xev, _not_ going
to console/terminal/x on Ctrl-Alt-F7 , where the xscreensaver unlock
password entry dialog is (it seems) activated by these events:

I waited for over half a minute (no other xev events) before finally
going to X (Ctrl-Alt-F7), and sure enough the password screensaver
unlock dialog was well on its way to timeout (I have a 1 minute
timeout set), so clearly the above xev events (which displayed rapidly
one after the other) are indicative of what triggered the screensaver
unlock dialog.

This has never happened before - only since my last sid upgrade (maybe
a week ago or so).

Is anyone able to decode the above events?
