not-yet-implemented things worry me. When can we expect this to
happen, and how big and ugly will it be?
I'm not seeing many (any) reviewed-by's on these patches. I could get
down and stare at them myself, but that wouldn't be very useful. This
work goes pretty deep and is quite security-affecting. And network-afecting.
Can you round up some suitable people and get the reviewing and testing happening
please?
