Summary:
In certain nested MOCs configuration, NSFetchRequest fetchBatchSize is ignored. This seems to be the case when the main context does not have direct access to persistent store.

Code example modified from "iPhoneCoreDataRecipes" is provided as example.

When the problem happens, SQL log looks like what's found in "limit clause missing"

Steps to Reproduce:
Use attached sample data in folder - 76BFE3FF-2C24-4AAF-B18C-E229F9BA4DE7
Run the attached sample code for different MOCs setup starting at RecipesAppDelegate.m L128
Observe the SQL debug log generated

For "single context" and "main context as parent context" cases, fetch request behaves as expected.

For the other cases where the main context doesn't have direct access to the persistent store, fetchBatchSize is ignored

Expected Results:
fetchBatchSize should be honored. i.e we should see LIMIT clause added in the SQL.

Actual Results:
LIMIT clause is not found.
