import aiohttp
import aiothrottle

def load_file(url):
    response = yield from aiohttp.request("GET", url)

    data = yield from
    with open("", "wb") as file:


# setup the rate limit to 200 KB/s
aiothrottle.limit_rate(200 * 1024)

# download a large file without blocking bandwidth
loop = asyncio.get_event_loop()

# unset the rate limit
