Apologies, but the approach I'm taking is very significantly different so it would be problematic in terms of patch provenance to do this :( I will make sure to credit you directly in the commit message so there is proper attribution, this patch and follow up stuff has grown a lot (been working on it all of yesterday afternoon/evening + this morning) and need to ensure the stable stuff is backported etc. Thanks for your contributions here, very much appreciated, and sorry to have messed you about on this! Cheers, Lorenzo
