It's a ton of new code and what I'm not seeing in here (might have
missed it?) is a clear statement of the value of this feature to our
users.
I see hints that CRIU would like it, but no description of how valuable
this is to CRIU's users.
So please spend some time preparing this info.
Also, are any other applications of this feature anticipated? If so,
what are they?
IOW, please sell this stuff to us!
