It's a bit puzzling, frankly, to see a nice example of engineering
(which is what I consider a consistent DB design) foiled by a
performance and practical issue. :(

That's it then. I'll ask the designers of the application to consider
implementing the background delete, since it's obvious I can't solve
it satisfactorily solely on the DB side.
