consider a sleepyhollow wrapper api layer

[weisjohn]

Frankly, the PhantomJS API is too hard. A high-level sleepyhollow API could exist which utilizes sleepyhollow-node/phantom as the bridge.

For example, render is not async, but it does block, but it does not block until the image is written to disk, rather it just blocks until some Qt abstraction flushes: ariya/phantomjs#11084 There's a work-around in ariya/phantomjs#11780 which demonstrates how they determine if the render really has completed. ( vvavrychuk/phantomjs@63955e3#diff-189aee7cd62ea62e8a4e9979ddbbe152R2030 ) This could simply be implemented in an abstraction.
