I've updated PR with complex fix for #1 & #2. Could you please review my changes?

BTW, I see a minor mem leak issue (checked but not fixed at my PR):

In case of merged exchange, joining node will create client latch which will never be removed
from clientLatches map.

That latch ignores since {{localJoinExchange() == true}}, but it is a mem leak I think.

was (Author: avinogradov):
See the bug, interesting thing is that bug works :)  

let me check it deeper.
