upstream keepalive - call for testing

[magicbear]

I have run the nginx 1.1.2 via this patch for 7 days, except for one
days have a large DDoS so I restart nginx for several seconds, it was
very stable to work.
Handle about 70million request without problem happen, I think the last
problem may be have a memory corruption, you are right.
I will check that server when have times.
Thanks for your hard work.
