Can a timing chain seize an engine?

A timing chain is supposed to last the life of a vehicle, within reason. But if it breaks, the pistons will come up at the wrong time and crush a bunch of the valves, leaving the crankshaft unable to turn. That would lock up the engine, just as if you had run out of oil and melted the crankshaft to the bearings.
