      Watch under performance tools to see the memory growth, which is very rapid. You will want to ^C that before it eats all your memory.

      While experimenting with VS2019 for faster builds, we ran the unit tests and found that they terminated via OOM.

      Some initial investigation suggested misbehavior in the alarm subsystem, but we didn't dig too much further.

      It is possible that it is another manifestation of https://developercommunity.visualstudio.com/content/problem/861451/possible-codegen-issue-after-attempting-to-upgrade.html, but in case it is not, I'm filing the ticket to track it.
