Saw the following tests fail after the PR #2491 merged, perhaps related.

@hsaraogi the PR you referenced is unmerged

[hsaraogi]

Oops, so there might be some other cause here, but I saw this flake for the first time.

[hsaraogi]

If we see it again, we should look into this.

[gsheasby]

Hit this on internal build palantir://7000 (ironically, I was looking into fixing a flake...)
