PS1: 
Sergii, thanks a lot for the patch, that's a great help. You said it's fine to take over, I think I will take the offer.
There are few small changes that can be extracted in separate small commits (like updating comments), I would do this first if you don't mind. This would make the patch smaller and also more focused.
I added comments, mostly because I want to understand your idea better. If you could reply, that would be great, thanks!
