Shmuel and I---What's new?---may disagree; or again we may not. Serialization is best accomplished in layered fashion with supervisor assistance; and for this reason Dijkstra's unlayered semaphores are, at best, misbegotten.
That said, serialization can be implemented in ugly, resource-hogging fashion with just TS. Indeed, it once was, albeit in multilevel fashion.
