Just a followup on this thread. Thanks for those that gave it a shot and provided feedback. Results look really good. There are some minor knock-on effect bugs - we're tracking those here https://bugs.launchpad.net/bugs/+bugs?field.searchtext=nonblockswap All of which have some level of debug and proposed solution. No doubt this is an improvement even with the minor "regressions", so I plan to move forward in a landing attempt, with the team remaining focused to clean up the regressions.
