I was a little busy with deadlines at the time but I saved the database in it's slow configuration so I could investigate during a quieter period.

I'll do a restore now and see whether I can remember back to April when I came across this issue.

Oh?  Could you provide a test case for this?  I can certainly believe

it shouldn't take a long time to do it.
