I'm not sure if this is a bug or intended behavior, but the RTS options passed to Gulp only have an effect on the compile command. We are using -N2 to reduce problems in CircleCI, but since the RTS flags are only applied to the compile command, bundling takes almost 3 minutes.

Maybe the RTS options could be applied to bundle as well, or an option could be added to specify RTS flags when calling the plugin from JS?
