nothreading use single threaded

threading:
	# ThreadingMixIn.daemon_threads indicates how threads will behave on an
	# abrupt shutdown; like quitting the server by the user or restarting
	# by the auto-reloader. True means the server will not wait for thread
	# termination before it quits. This will make auto-reloader faster
	# and will prevent the need to kill the server manually if a thread
	# isn't terminating correctly.
