dismissing SSHUDView leaves hidden view around.

[axfree]

In its _removeWindow method, the view should be removed from its superview(_hudWindow). unless we do this, the view will never have a change to deallocate.

• (void)_removeWindow {
  // Apple doc says, you should never invoke resignKeyWindow directly
  // [_hudWindow resignKeyWindow];
  _hudWindow = nil;

  [self removeFromSuperview];

  // Return focus to the first window
  [[[[UIApplication sharedApplication] windows] objectAtIndex:0] makeKeyWindow];
  }

Currently, dealloc does not care the view is dismissed or not, so I think calling removeWindow again from dealloc is not a good idea.

• (void)dealloc {
  [[NSNotificationCenter defaultCenter] removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];

  //[self _removeWindow];
  [_activityIndicator release];
  [_textLabel release];
  [_completeImage release];
  [_failImage release];
  [super dealloc];
  }
