I guess you're referring to PSC's:
+setMetadata:forPersistentStoreOfType:URL:error: ?
Is that the only one that writes to disk immediately?

What about PSC's:
+setMetadata:forPersistentStore:
Is the "Setting the metadata for a store does not change the information
on disk until the store is actually saved" comment in the docs correct
for this method?
