This is what I've made (suppose you receive a data from a

1) You receive the packet
2) Put it into a temp array
3) When you reach a number x of messages you can call the save
function
The save function repeats these statements for each packet from the
array:
1) Perform insertObject in a second managedObject (connected to the
same persistent store)
2) Get the list of objectID of the object and save it to another array
3) When all packets was saved perform linkMessages function into main
thread passing the objectids array
According to <http://developer.apple.com/documentation/Cocoa/Conceptual/CoreData/Articles/cdMultiThreading.html#//apple_ref/doc/uid/TP40003385-SW3

if the managed objects were saved. I've never used saving in another
object context,
I don't know if it is causing another headache ...
Maybe it is easier to just pass the data to the main thread and perform
the insertion only in the main context?
The recent thread <http://www.cocoabuilder.com/archive/message/cocoa/2008/3/30/202687

some interesting posts on this topic.
