Looks like this fixes all the builds except docbuild, which should be fixed by #40542

This fixes the memory issue I noted on gitter:

Anyone else seeing larger memory usage when running the tests? Each pytest worker is using close to 4 GiB on me, I recall this being 2 GiB not too long ago.

Now that you mention it... about 1.3 GB at the end of collection, 6.04 by the time it hits 1%! 2GB matches my recollection of what ive seen recently pre-yesterday
