I realize that it's difficult. I was under the impression that this is a
well-known problem, since it appears to be well-known to the guys at
IBSurgeon. Apparently not. It's probably highly intermittent,
considering I have dropped a lot of tables in non-exclusive mode through
the years, before I got a corruption and learned about this problem. A
test case? Yeah, well, I could try... But I think it would be better if
the dev team were to communicate with those who know the problem a lot
better, i.e. please talk to IBSurgeon.
