Status update for a commitfest entry.
It looks like there was no real progress on this issue since April. I see only an experimental patch. What kind of

David, are you going to continue working on it?
Can you, please, provide a short summary of the problem and list open questions for reviewers.
The new status of this patch is: Waiting on Author
