Not sure if this is important, but I've discovered that I can get the desired
behavior if I force v4l1compatability like so:

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libv4l/v4l1compat.so avconv -f
video4linux2 -i /dev/video0 out.mkv

This will capture normally, and will exit when I hit ctrl-c (whereas the
aforementioned issue prevents any kill signals when run without the preload).
