This has the drawback that user events (keypresses and mouse clicks) will 
*also* be processed, which may not be what you want during a long operation, 
depending on how you display that state. If you pop up a modal dialog with a 
'cancel' button, then yes, QApplication::processEvents() is the right thing 
to do. Otherwise, it's preferable to use

QEventLoop::processEvent(QEventLoop::ExcludeUserInput |
          QEventLoop::ExcludeSocketNotifiers,
          maxTime);
