Hi russell,

There's no stable/official internal API, and there probably won't be.
We try not to encourage propagating new, ad-hoc standards that other
Rack servers do not support.  Sometimes it's not easy to avoid (e.g.
async.callback + EventMachine stuff), but we try.

However, since the config file is Ruby, you can always use a global
variable in your config file.

So something like this:

  Rainbows! do
    client_max_body_size($client_max_body_size = 200*1024*1024)
  end

If you have more variables you want to set, I know some folks
that use a global hash object or Struct, too.
