           Platforms interpret the value of MAX_CONNECTION_QUEUE_LENGTH differently.  Some platforms interpret

           stress from multiple clients with multiple requests, toggling this number may prevent clients from
           being dropped.  Instead of hard coding the value, we allow an environment variable to be set which
