Ah yes, that's it! We are archiving WAL, and I imagine what happened easily outran the pace of archiving. There was an exponential backoff between the retries, so although I could imagine rapid-fire retries filling disk with WAL before checkpoint running, I was having a little doubt about that happening in this case. I'm sure it was the archiving.
