    - This patch fix the race condition of double barrier and avoid the herd effect.
    - To focus on the core logic and keep the codes short and clean,don't consider some parameters
check,connect loss,the timeout for wait ....etc.The thoughtful codes can be found in the implements
of `DistributedDoubleBarrier` of `curator-recipes`.
    - For test,you can change the `QTY` in the barrierTest from small one(1,2,3) to large
one(1000,5000,10000),then observer the printed log to check the correctness of this patch.
