At the risk of stating the obvious, the simplest thing is to stop using COW with compression for torrents. It's fundamentally not useful to have many small in-place writes, irregular compression and not encounter insane levels of fragmentation, which - at least in the current state of btrfs - is known to cause long stalls. Some fixes for that will be in 4.4. Until then just do yourself a favor, stop doing the wrong thing and put torrent downloads into a directory where they won't get COWed.
