I've been looking at these failures:

1. The code being changed is unrelated to the failing tests.
2. I cannot reproduce the failures locally.
3. I've found some things to clean up in the test code, but nothing that
I can flag as a race condition.
4. I can't find any timeout issues that look relevant either.

There's obviously something different about the build environment, but I
don't yet know what.

I'll be submitting my cleaned up code shortly and will watch the test
results with interest.
