I don't start observers in -awakeFromInsert or -awakeFromFetch. I start
them on demand, and in -awakeFromSnapshotEvents: with
NSSnapshotEventUndoDeletion
(I ignore the other flags). I think the best place to start observers
depends on how the objects are used.
I stop some observers in -willTurnIntoFault, and others before that. It
depends on when I know that I no longer need the them.
