[RFC/PATCH] Bundler/Sandbox documentation updates

Hi Eric,

I tested this out:

- in the before_exec and after_fork I log PATH GEM_HOME GEM_PATH 
BUNDLE_GEMFILE for inspection after deployment

- deploy latest release, make sure to shutdown unicorn, then start cleanly

- prune all releases, except the last one

- deploy latest release again (which only sets the BUNDLE_GEMFILE env var)

I've tried this a few times, and everytime I get something like this:

https://gist.github.com/331b0decab62fd58483c

If I revert back to setting the GEM_HOME, GEM_PATH and PATH in the 
before_exec it works fine.


PS. When deploying I use USR2 followed by QUIT


Cheers,
Lawrence
