-Some last few things to do before release.
-
-- Handle/investigate the HTTP client pipeline errors
-- DB should not always restat files (especially for expired hashes)
-- remove missing files at startup (in DB's removeUntracked)
-- when files modtime but not size changes, rehash them to be sure
-- remove files from the peer's download cache
-- update the modtime of files downloaded from peers
- - also set the Last-Modified header for the return to Apt
-- make the DHT timeouts configuration parameters
-- refresh expired DHT hashes concurrently instead of sequentially
