Sashiko behaved unusually. "Note: The format of this report is altered
due to recitation restrictions. Direct quotes from the original patch
are omitted, and a free-form summary is provided instead.".

Roman, what's that all about?
Thanks, I'll add this to mm-new for some testing. Review is thin at
this time, but we have a large and dedicated band of swap maintainers,
so I'm sure that will change ;)
I understand that there are some architectural/directional differences
amongst the team (or there used to be), so please don't be shy about
weighing in if you think we should be taking things in a different
direction.
