[libtorrent] Speed greater than limit

[Maks S. <sc...@vi...>]

Hello,
I'm tring to use libtorrent library and I have a some following problem.

I create torrents with default settings and set them limits (e.g., 100Kb) as
  torrent_handle.set_download_limit(limit);

And when I ask speed for the current torrent:
  torrent_handle.status ().upload_payload_rate
sometimes I get greater value then the limit (e.g., 200Kb or 300Kb).

What's wrong? Why my torrent limits aren't applyed?

Best wishes,

Max Shipko
