I just launched "tad 311_Service_Requests_from_2010_to_Present.csv" (a 10GB dataset from data.cityofnewyork.us) and it ate up all my memory without ever showing any data. "vd 311_Service_Requests_from_2010_to_Present.csv" shows the first rows instantly, and I can start rearranging columns while it is still loading, and I can press Ctrl-C to stop the load (and the rows already loaded are still available). No config or tweaking needed.
