AFIncrementalStore

@JosephLin

Sorry to contact you here, saw your work on AFIncrementalStore (AFbackgroundFix branch), but could not find a way to add comments or issues there..

I am also trying to improve performance of AFIncrementalStore, and was looking at similar changes that you did.

I am running into an issue with a change we both made, and wanted to see if we could our brains together on that one:

Looks like the best performance gain is in executeFetchRequest, by changing
[childContext performBlockAndWait:^{ [self insertOrUpdateObjectsFromRepresentations...

into

[childContext performBlock:^{ [self insertOrUpdateObjectsFromRepresentations...

However, I am running automated tests where I keep sending the same request every couple of seconds, and that change seems to make the sync eventually crash.

Although it is hard to pinpoint the actual crash as it doesn't crash gracefully, it seems as if the problem happens around this line in insertOrUpdateObjectsFromRepresentation...:

managedObject = [context existingObjectWithID:managedObjectID error:nil];

I did wrap that call into a performAndWait block, but it doesn't help.

Anyway, I wanted to see if you experienced similar issues when running multiple query in a row quickly, let me know!
