that could be a way, but I wonder why the current code does not work: it 
breaks out of the operation loop when pause or stopped is set.

Since pause only breaks out, but the exectur remains there as well as 
the code in

- (IBAction)pause:(id)sender
...

      [pauseButt setTitle: NSLocalizedString(@"Pause", @"")];
      [stopButt setEnabled: YES];
      paused = NO;
      [executor performOperation];

...
should just resume operation, since performOperation will work on the 
same "files" array which contains the remaining work.

but what happens is that pressing the button does not get into

- (IBAction)pause:(id)sender

again, why? The button gets pressed thus gui is still responsive, it 
should be almost in its initial status (I checked with top and see that 
the worker thread dies with pause and the application returns 
single-threaded).

Where does my performAction go??
