title: Libtorrent setting download_limit/upload_limit is not working
body: <p>I want to rate limit my download/upload speed in my libtorrent client. I am using the following code for this.</p>
  
  <pre><code>params = { 'save_path': '.', \
             'storage_mode': lt.storage_mode_t.storage_mode_sparse, \
             'ti': info, 'flags': 0x020 }
  
  h = ses.add_torrent(params)
  h.set_download_limit(100)
  h.set_upload_limit(100)
  h.resume()
  </code></pre>
  
  <p>It should download the data at 0.1 kb/sec, but still it is downloading the data at the speed of around 1500 kb/sec.</p>
  
  <pre><code>100.00% complete (down: 1576.0 kb/s up: 55.0 kB/s)
  </code></pre>
  
  <p>Anything I am missing ?</p>
