* Introduce environment variable proxy-initial-not-pooled to avoid reusing
pooled connections if the client connection is an initial connection.
This avoids the "proxy: error reading status line from remote server"
error caused by the race condition that the backend server closed the
connection after the connection check on our side and before our data
reached the backend. Yes, this downgrades performance, especially with
HTTP/1.0 clients. Hence it is configurable and off by default.
