Sorry I didn't follow up on this. Things looked better after the patch but I was seeing a strange issue where the memory was being reduced to some minimum and the balloon would never shrink so the available memory was seemingly locked from then on. I ran out of time to investigate this later behaviour and didn't have the time to check if it had always been the case but I think I see other patches saying you nailed it and other issues. Do you have a published git tree with all these pieces in or have they already been mainlined?
