ConnectionResetError when close browser, but not all static files was fetch

[AlexanderMartynoff]

While receive a large static file, if you break the connection, an exception throws:

  File "/home/user/.virtualenvs/local/lib/python3.6/site-packages/aiohttp/web_protocol.py", line 429, in start
    Yield from resp.prepare (request)
  File "/home/user/.virtualenvs/local/lib/python3.6/site-packages/aiohttp/web_fileresponse.py", line 232, in prepare
    Return (yield from self._sendfile (request, fobj, count))
  File "/home/user/.virtualenvs/local/lib/python3.6/site-packages/aiohttp/web_fileresponse.py", line 120, in _sendfile_system
    Yield from writer.sendfile (fobj, count)
  File "/home/user/.virtualenvs/local/lib/python3.6/site-packages/aiohttp/web_fileresponse.py", line 74, in sendfile
    Yield from fut
  File "/home/user/.virtualenvs/local/lib/python3.6/site-packages/aiohttp/web_fileresponse.py", line 40, in _sendfile_cb
    N = os.sendfile (out_fd, in_fd, offset, count)
ConnectionResetError: [Errno 104] Connection reset by peer

In the future, when you try to get a large file, an exception throws:

RuntimeError: File descriptor 13 is used by transport <_SelectorSocketTransport fd = 13 read = polling write = <polling, bufsize = 0 >>
