I've a fix for this in my personal tree now. As mentioned in the
cover letter, patches 2 + 3 are really more of a RFC for now, the
goal for now is just to get patch 1 merged.

I will send out a new version of this patch after patch 1 is merged
(or when patch 1 needs a new revision).

Regards,

Hans
