New code, new features, new problems. E.g. public PR1323306 describes a 
BGP stuck situation. (And the fixed code should address as well a - 
hidden - PR, which causes down/stale sessions, leading to stuck routes 
even without a both-side GRES event). All very, very special cases ... 
but some of us will find / get hit by them (unfortunately).
