Michal acked it before we had most of the discussions and now he is
proposing an alternate version of yours, a patch that you are even
discussing with him concurrently in another thread. To claim he is
still backing your patch because of that initial ack is disingenuous.

No, he's not and I'm sick of you repeating refuted garbage like this.
You have convinced neither me nor Michal that your problem is entirely
real and when confronted with doubt you just repeat the same points
over and over.
The one aspect of your change that we DO agree is valid is now fixed
by Michal in a separate attempt because you could not be bothered to
incorporate feedback into your patch.
