// Problem...
// I want to do bulk processing against a paginated API
// Spawning a go routine per page DOS's the site, so I need throttling
// Instead send the offsets to a channel and spawn a number of workers
// to process the pages
// 
// I can't just use 2 channels, because I want to easily consume
// the output and signal done with close(output) and double closing
// a channel causes a panic. I also don't know how many responses I'm
// going to get out, so I can't consume a fixed amount.

   This program contains a simple micro-benchmark for a Disruptor [1] like
   event buffer (or at least what I think that Disruptor might be). There
   isn't any kind of API yet and this test is currently limited to a
   single producer - single consumer architecture, but generally the 
   architecture of Disruptor is also well suited for multiple producers and 
   consumers.
