I'm somewhat sceptical.  It seems to be limited to very few use 
cases, and also there are lot of corner cases to consider.  In 
particular, as far as I see the patch in question will break 
miserably when using SSL (not to mention it won't work on 
non-linux systems with TCP_FASTOPEN).  It might be much better 
idea to use persistent connections to upstreams instead.
