I'm forwarding this to the hackers list, because it presumably is an issue
to be addressed in the code for rolling back an aborted transaction.  I
suppose that there is nothing there to handle the case that the index file
runs out of diskspace and that therefore the index became corrupt.

Mind you, I'm just guessing!

There was nothing at all out of the ordinary about them: I think they are not
likely to be relevant to the problem.
