`async/await` with ES6 Generators & Promises

This vanilla ES6 function async allows code to yield (i.e. await) the asynchronous result of any Promise within. The usage is almost identical to ES7's async/await keywords.

async/await control flow is promising because it allows the programmer to reason linearly about complex asynchronous code. It also has the benefit of unifying traditionally disparate synchronous and asynchronous error handling code into one try/catch block.

This is expository code for the purpose of learning ES6. It is not 100% robust. If you want to use this style of code in the real world you might want to explore a well-tested library like co, task.js or use async/await with Babel. Also take a look at the official async/await draft section on desugaring.

Comparing node.js GPIO implementations

Here are two simple programs testing the performance of my rpio library against popular alternatives which use the /sys interface (with the number of npm stars indicated for a rough idea of popularity).

rpi-gpio (9 stars)

This test is based on an example on the rpi-gpio page.

As modules which uses /sys depend upon asynchronous behaviour they require callbacks to ensure that the next operation starts only when the previous one has completed.
