Thanks Jim...
What if the attribute to be changed in the background is an ivar
attribute, which is not represented in the data model? Is it safe to
update the attribute directly from another thread without having to
use private contexts and local copies of managed objects?
(I don't think the private context / notification approach actually
works for ivar attributes, since the attribute doesn't actually exist
in the data model...)
