Panic when an older subprocess is already running when trying to start a new subprocess. This situation was already detected, but instead of failing the current task (and keeping the Worker running), the Worker now shuts down completely. When running as a systemd service, the Worker will automatically be restarted. When this panic occurs, the Worker still signs off at the Manager, causing its current task to be returned to the queue. That way another Worker (or this one, after the restart) can retry it. This is basically a hack to work around the issue that sometimes Blender is running twice on the same machine.
