add separate limits for connection buffers
allows specifying a megabyte limit for either response objects or read
buffers. this is split among all of the worker threads.
useful if connection limit is extremely high and you want to
aggressively close connections if something
happens and all connections become active at the same time.
missing runtime tuning.
