Thanks for the patches - this has been on my TODO list but you beat me
in getting there first :). Are these for 4.12?

I have given the series a quick try and these currently break the
functionality. I am investigating the failures, so will mostly need some
additional changes. Let me know if you want me to take up posting of the
v2. Meanwhile, I have added some comments on the patches.
