Have the CLI run the checks in parallel

Is there a strict reason to run them in serial?

This wouldn't really do anything unless you also apply a utility that runs your JS across multiple threads / cores. I'd suggest something like grunt-parallelize.

Thanks for the advice. Is there any reason not to load the files concurrently as opposed to sequentially? https://github.com/palantir/tslint/blob/master/src/tslint-cli.ts#L179-L183
