Did this message really appear twice? I'm guessing, but perhaps you're
seeing a threading problem. I doubt it's healthy for more than one
thread to use the same tempfile name. Perhaps you had three threads
generate the same name, and when one of them closed the file descriptor
you got this message from the other two.
