You're right, that could be it - in a way at least, the issue is replay not
catching up within 180s, so it'd have to be the data volume growing, I think.

But it doesn't look like the regression volume meaningfully grew around that
time?

I guess I'll try to write a buildfarm database query to extract how long that
phase of the test took from all runs on my menagerie, not just the failing
one, and see if there's a visible trend.
