Platforms interpret the value of _maxConnectionQueueLength

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

_maxConnectionQueueLength = 15.
