Support persistent connection, even in single thread mode (i.e concurrency=none).

Browse Source 
Warning: as there is no concurrent request handling in single threaded mode,
            it is recommended to either set the keep_alive_timeout to a small value,
            or disable persistent connection by setting max_keep_alive_requests to 0.
Change the default keep_alive_timeout from 15 to 5 seconds.
Accept -1 as value of max_keep_alive_requests to have unlimited number of request in the same persistent connection.
