[Buildbot-devel] lazy logs a bit too lazy and que'ed requests not being processed

[Thomas Middeldorp]

I can confirm "proxy_buffering off;" is what fixed this for me in 0.8. In my 
setup I have /waterfall behind a proxy_cache (you could add other locations if 
needed) and then / is a straight proxy_pass with buffering turned off.
