So I took some screenshots of `xrestop` while chromium was in the google
meet.

There was an "unknown PID" listed, but given other characteristics of
that line, I assume that it is related to chromium.

Here are some of the columns over time:

         Pxms     Misc    Pxm mem        Total
12:09:28 46749    9       18815550K      18815550K
12:10:38 55508    9       20869237K      20869237K
12:13:06 71707    10      24679650K      24679650K
12:17:06 93990    11      29960587K      29960587K
12:30:17 157769   11      45126262K      45126262K
12:35:06 175712   2       49397850K      49397850K

The last one, 12:35:06, is just before I closed chromium. It stayed
frozen like that, the xrestop app froze just like the rest of the
desktop (I was running it over ssh, so I could still ctrl-c it, but it
was frozen).

Attached is the last screenshot.
