  This is exactly why we shouldn't include this code in CVS yet.  
processEvents() is going to cause us huge nightmares because we will receive 
update events from the threads, among other things.  I spent lots of time 
removing these because of the crashes and bugs they introduced in the past.

+void KstApp::slotUpdateProgress(int iTotal, int iStep, const QString &msg) {
+  if (iStep > 0) {
+    if (!_progressBar->percentageVisible()) {
+      _progressBar->setPercentageVisible(true);
+    }
+    if (iTotal != _progressBar->totalSteps()) {
+      _progressBar->setTotalSteps(iTotal);
+    }
+    _progressMsg->setText(QString::null);
+    _progressBar->setProgress(iStep);
+    _progressMsg->setText(msg);
+  } else {
+    _progressBar->setPercentageVisible(false);
+    _progressMsg->setText(msg);
+    _progressBar->reset();
+  }
+
+  while (kapp->eventLoop()->processEvents(QEventLoop::ExcludeUserInput));
+}
