Last change on this file since 83967 was 83741, checked in by vboxsync, 5 years ago

Guest Control/Main: Implemented using multiple attempts to close a guest session in IGuestSession::close() and let the user know what's going on. Some bigger guest control process setups may require longer timeouts for getting a guest session closed [build fix]. bugref:9320
