1 * Maybe a bug in read truncation by pending chunks causes that occasionally glitch in VLC?
2 * Might need to reorder pieces by bytes left when hashes pass.
3 * When a piece has zero bytes left, it could be removed from pieces by bytes left, removing O(n^2) overhead searching for incomplete pieces for every connection.
4 * Make torrent read requests higher priority than everything else?
5 * I think the high-low water is broken with responsive download strategy.
6 * Properly encapsulate the mmap/span stuff.
