Our starting point was that we have a very little filled disk-cache and
want to switch the whole German wikipedia traffic  to our own
tileserver. Because of that we have during the day times a very lot of
cache misses (we redirect the 404s to the main osm tileserver on the
limit. We planned to have the server catch up during the night times but
for this to work we needed it to record all the misses that happened
during the day.
We've now gone another road: we took all the coordinates of all
wikimedia articles of interest (Tim did some magic filter foo here) and
threw it against tirex-batch before we switched the tile source over.
This way reduced the number of 404s drastically but even now the number
of dirty tiles in the queues was yesterday above 1400 .
