Large delays between upstream_response_time and the proxy's runtime

[Zev Blut]

Hello,

We are running into a problem where mongrel/unicorn's runtime can be 
significantly different from nginx's upstream response time.
This means we can wind up with odd delays and excessive request queuing 
if the upstream_response_time is high while our actually proxy response 
was low.

We worked on this a while back on the ML here:

I noticed that Maxim's patch has not been applied to the 0.6 series.
Was this patch incorrect or have other problems?

Thanks,
Zev
