-Add all cache files to the database.

-All files in the cache should be added to the database, so that they can

-that shouldn't be added to the DHT.

+Improve the downloaded and uploaded data measurements.
+
+There are 2 places that this data is measured: for statistics, and for
+limiting the upload bandwidth. They both have deficiencies as they
+sometimes miss the headers or the requests sent out. The upload
+bandwidth calculation only considers the stream in the upload and not
+the headers sent, and it also doesn't consider the upload bandwidth
+from requesting downloads from peers (though that may be a good thing).
+The statistics calculations for downloads include the headers of
