Review Comment:
   Good to know, thanks for the info,  could you provide more info on when a 
re-ordering (not so interested on duplicates for my use case) can happen, if 
there is a really unlikely edge case we may live with it. 
   On the other hand, do you have an idea of how slow is using using 
idempotency vs  in flight requests =1?
