It is more or less fine to use dispatch()/dispatch_queue() in a multi-threaded application as long as one deals with tear-down appropriately and dispatches the right queue on the right thread. See bug 91767 and bug 91769 for more details. We aim to fix these issues shortly after the coming release. -- You are receiving this mail because: You are the assignee for the bug.
