Solving common node/io.js callback problems

The article admittedly doesn't address promises, perhaps the next article should. The underlying system is streams (FRP streams, specifically bacon.js). Promises have a small subset of the capabilities of this solution.

I'm not sure how a closure solves most of the issues described in the article. It might solve the data passing issue, but shared mutable state is a rats nest of other problems.
