For this reason I'd really like to get this or a subset of it into mainline as soon as possible. This patchset (or rather the -v7 version) has been running on my laptop for a couple of weeks without problems. I've also verified that it solves the fuse and loop issues. I have some qualms about the complexity of various parts though. Especially the "proportions" library, which I'm having problems understanding. I'm not sure that this level of sophistication is really needed to solve the issues with the old code.
