Just a tidbit - I don't think there's any quirks involved. The general idea is this: NSTask creates a run loop source on the main thread, and spawns a second thread to watch the process for termination. When the process terminates, the secondary thread signals the main thread's run loop (via CFRunLoopSourceSignal()), and the run loop source's callback then executes on the main thread, which issues the notification. On 10.5+, this can be done trivially using kqueue and CFFileDescriptor.
