Bug#741893: general: System unresponsive after large torrent download to btrfs

[Mike <mgreger@cinci.rr.com>]

Package: general
Severity: important

Dear Maintainer,

        Downloading a large torrent (30GB, 10000 files) using transmission-gtk
onto a btrfs filesystem (mounted as the root filesystem) causes the system to
become unresponsive after a very short period of time. Tried marking the
torrent directory with the no-COW attribute before starting, but that made no
difference. System had to be powered off to shut down.
