I thought I saw some patch today that to save more artifacts.

But the bottom line is that we don't emit enough stuff from any of our tests to debug them 
from logs -- we're too used to using other methods.

CFI (control flow inspection/validation/somesuch) adds checking along call paths, which 
may affect timing.

This is almost certainly some sort of race condition.

Not as is, no.  You'd have to create a new CI job, and for that you'll need advice beyond 
myself.
