Platforms interpret the value of MAX_CONNECTION_QUEUE_LENGTH differently. Some platforms interpret

the value literally, while others multiply a fudge factor. When the server is under

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

specifies a number greater than the maximum concurrent client connections possible. If this environment

var is not specified, then MAX_CONNECTION_QUEUE_LENGTH = 15.
