I wasn't out of space--unless possibly Xapian caused some transient
spike in disk use that was freed when it died. The system does run
without a ton of free space though, maybe 100 MB for a Xapian database
that is ~300 MB total.
I didn't get any disk errors either. This is on a VPS that could
conceivably be hiding some errors.

It turned out that sup-dump still worked. Probably some index was
corrupt but the data could still be walked. So I was able to restore
without losing any data. (Well, it did use most of the 160 MB of memory
on the VPS.)
