Sigh, I forgot to shut down Chrome overnight, and my system is
deadlocked again. I can still switch virtual desktops in X11 and a
running xterm accepts keyboard input, but it is 18:35 now and I see that
my X11 clock has last updated at 17:18 and conky is stuck at 17:14:11

my top-in-a-loop is stuck here and no longer loops:

I'm unable to scroll back the vmstat -m output in my tmux pane (running on a
different system, this is super strange), so all I can show is this:

Now what?

The xterm I have running locally with a stuck top is showing the top 3 chrome
processes in pfault state and it has "Swap: 11M In" in the header, so clearly
11.x is prone to deadlock during page faults and or swapping. It has last
updated on 17:14:13 (compare to the other top at 17:14:10 not showing pfault
state yet).
