I think I just read the discussion to hastily as it was rather long,
sorry about that.

After really long or confusin discussions, just to help the maintainers
and also avoid miscommunication between participants, it's usually a
good idea to summarise the conclusion. If us maintainers need to figure
out the conclusion ourselves from a long discussion we are bound to make
mistakes, just like I did here.

So something like this would help me a lot:

"Kalle, please drop these patches. I need to work on these a bit more."


"Kalle, me and John came to agreement about foo. So these should be good
to apply."

If you both are happy with the patch, I'm happy to take it :)

I actived the patch again in my queue by moving the state from Deferred
to New:


If all goes well I'm expecting to apply it later this week.
