Couldn't really test since make is failing for me right now. The idea is to be more node-like in the interface, yet still allow extensibility of the constructor/prototype if needed.

What is it failing from? I've only tested the latest version on linux. It might be missing some osx specific headers.

Anyway, looks good to me. More reminiscent of child_process.spawn.
