> We introduce an {{os::rename}} abstraction to {{stout}} in order to support
> atomicity and validity of checkpointed files. Writing directly to the
> checkpoint file can leave the file in a corrupted state if either: the slave
> crashes while writing, or checkpointing encounters an error and the slave
> crashes before the partially written file is removed. We should checkpoint to
> a temporary file instead and use {{os::rename}} to atomically move it to the
> desired path.
