 I have implemented NSJSONSerialization support for the multi_json gem.
 The implementation went fine, and I could finish a pretty decent MultiJson
 Engine standing on the shoulders of the Cocoa framework.

 I managed to implement all features that a MultiJson Engine requires, and
 the specs are all green.
 But I keep getting those malloc warnings/errors. They make me feel
 uncertain about the stability.

 {{{
 $ git clone git at github.com:Overbryd/multi_json.git
 $ cd multi_json
 $ git checkout macruby_nsjsonserialization
 $ macgem install rspec simplecov yajl-ruby json
 $ /usr/bin/rspec spec/
 ...Warning: multi_json is using default ok_json engine. Suggested action:
 require and load an appropriate JSON library.
