It's distressing for both of us how slow I am to review these, sorry.
We have just too many bugs in mm (and yes, some of them mine) for me
to set aside time to get deep enough into new features.

I've been trying for days and weeks to get there, made some progress
today, and hope to continue tomorrow.  I'll send my comments on 1/7
(thumb up) and 7/7 (thumb down) in a moment: 2-6 not tonight.

Trivia only, I haven't noticed any blocker; though I'm still not quite
convinced by memfd_create() - but happy enough with it if others are.
