Would it be worth adding a command to the union of possible events that
adds a pause?  As in:

-> { "execute": "input-send-event",
    "arguments": { "console": 0,
                   "events": [
                    { "type": "btn",
                      "data" : { "down": true, "button": "Left" } },
                    { "type": "pause", "data": { "duration": 10 } },
                    { "type": "btn",
                      "data" : { "down": false, "button": "Left" } } ] } }

that sticks a 10 ms delay between the other two events?
