DirectDruidClient openConnections may be samller than the real connctions between the servers

[BigRantLing]

Hi guys，
Our Druid version is 0.9.2.
When I was going to make some changs to code of DirectDruidClient , I found some original code confuse me. The openConnections is a variable means the connctions ammount of queryable servers. And it will increase after broker requesting a server.But it only represent the connection ammount between this broker and the server requested. When we use ConnectionCountServerSelectorStrategy to decide server should be requested,the broker will choose the server which openConnections is small. But, the real active connection ammount between the sever which has been selected and all brokers may be bigger than openConnections.
Is that right?
Thanks for reply.
