Drat.

It's really unlikely (I hope) that the clients running SELECTs had
anything to do with it. You had mentioned that you were busy making
manual schema revisions while this went on; that process seems more
likely to be the guilty party. But if you don't have the logs anymore,
I suppose there's not much chance of reconstructing what you did :-(

I spent much of this afternoon groveling through the deletion-related
code, looking for some code path that could lead to a deletion operation
deleting the wrong file. I didn't find anything that looked plausible
enough to be worth pursuing. So I'm stumped for the moment. We'll have
to hope that if it happens again, we can gather more data.
