Multiplexing requests is seldom done by <a href="http://www.fastcgi.com">FastCGI modules</a> and is even sometimes impossible because of bugs in them. Moreover, multiplexing is mostly useful if concurrent requests are handled by different threads while this library use a single thread to process all requests coming on a given connection.
