Thank you very much for following up, Reco. I had no difficulty
triggering a hard drive thrash (thank you, Linotype!), and the problem
is definitely memory-related. I managed to stabilise my system by
increasing the swap partition. Unfortunately, the hard drive didn't
stop thrashing and after an hour I gave up and hard-powered off. I
did, however, save this kernel log from 20 minutes into the OOM
https://paste.debian.net/1028268/ (link's good until 9 June)

So, as I think you suggested, it seems that OOM-killer isn't getting
in quickly enough to kill a program and/or not working correctly.

Suggestions?
