[MapProxy] mapproxy and mapnik2

[Luca Delucchi]

Now the mapproxy-seeds it's finished and it's possible to see the
tiles on the demo client. But when I zoom to a level zoom that I
didn't pre-rendering (for example 6) I obtain again the error of lock.
This could be a problem of mapnik when the request come from the web?
Someone never use mapproxy with mapnik?
