You can't unless you issue a -read..InBackgroundAndNotify method on the output file handle. Otherwise, if you're not reading from the pipe, it can fill up and block the task. Then you're deadlocked. Also, -waitUntilExit has the nasty problem of running the run loop in the default mode. On the main thread, that mode is likely to have various and sundry sources and timers scheduled on it. That means that they may fire during your call to -waitUntilExit, which can have unpleasant side effects that you weren't expecting, possibly including recursion.
