> Looking at FirstAvailable load balance policy, electedTarget access/update is not synchronised, 
> however, the chances of having some issues are very small. First, the proxy needs to be shared 
> by various threads before the electedTarget has been set, but as electedTarget already elected 
> randomly, the secondary effects of this lack of safety are none.
