Class A 330 diesel won't shut off

Always be very leery of diesels that won't shut down. A neighbor had that issue with his work truck (owned by his employer). He got home, pulled into the driveway and switched off. It kept running, and got going faster and faster. He even disconnected the fuel pump, but to no avail. Eventually, there was a big bang and the crankshaft appeared outside the engine, in bits.
The diagnosis was that the engine had started using its lube oil for fuel and only stopped when it had burned enough of it to starve the bearings and break the crank.
