as per RFC, you should do parallel forking to branches with the same q, 
but at the end of the day, it is up 2 you

if the branches have the same q, how do you want to order them ? 
registration time? this will be inconsistent as during re-registration, 
the order of those 2 branches will keep swap. Nevertheless, check
