Just my 5 cents.
FD bouncing between processes is obfuscating by design.
There are some situations, when we just can't do it otherwise. But 
sometimes it looks like overkill (I'm not contend about current 
situation since I haven't dig deep enough into it).
And I believe, that we have to try to simplify CRIU logic as much as 
possible.
CRIU is complicated enough already.
