suggest some fixes/improvements

While setting my nginx up and learning a lot from your config I found a few issues that I had to struggle with. While some are specific to my machine I am suggesting a few that might be good to improve.

First is to increase variables_hash_max_size. I'd think this is specific to me, but is a plain debian testing  install on a 1gb rackspace performance server and getting that with your config out of the box, might be godo to have it as default, wondering what you thing?

Then the other bits are related to the php-fpm status pages that needed some small tweaks matching your suggested php-fpm configuration.
