True. It's really useful with ruby on rails, because mongrel can just treat
one request at time.
upstream_fair (with weight-mode=peak) will only limit the number of

I do not know the weight-mode option. But it's the same principle. Instead
of returning an error, haproxy created a queue of requests.
