Config/Size Parameter Conflicts with OrderedOptions/Hash method

[wied03]

The config.react.size parameter, which is read in renderer.rb to control the size of the connection pool, is always ignored because size returns the size of the config hash (OrderedOptions inherits the Hash class and its size method), not the config setting itself. I will try and create a fork+pull request for this.

#153 should take care of this.
