→Start VNC server and application
* First, X software uses SystemV IPC shared memory to exchange data between server and application, thus you'll have to run the whole stuff in IPC namespace;
* Second, in order to be restored reliably, it's recommended to run VNC server, window manager and application in a PID namespace;
* Third, when started from shell they will inherit session ID and terminal from that shell, which might block dump.
