To Squ:
I read through all your posts today and, although several people have
asked you, I still don't see where you've confirmed that this garbage/
cleanup is indeed a performance issue. My recommendation remains that
you confirm this first, especially now that multithreading Core Data
has been put on the table as a "solution"...

BJ, I would omit the word "simply"
I'm not a Core Data expert (yet), but you will need to give the
background
thread a separate NSManagedObjectContext...
That's how I'd do it, anyway.
Well, not me. One last time, Squ: I'd step back and confirm that I
really need to do this. I find both of your assertions (1) that
leaving the garbage around for awhile is a performance hit and (2)
that cleaning it up in the main thread immediately is a performance
hit -- to be surprising.
