Cross browser setImmediate speed tests

gistfile1.js

/**
 * Did some performance tests using the absolutely awesome cross browser setImmediate
 * implementation at https://github.com/NobleJS/setImmediate.
 * 
 * I noticed that in Firefox performance of setImmediate remained steady and consistently
 * outperformed the setTimeout(fun, 0) trick. Chrome was a different story with performance initially
 * good but quickly diminishing. I found that if don't let Chrome use MessageChannel (the 
 * implementation it defaults to) it falls back to what Firefox uses and performance stabilizes. 
 * 
 * Below is test code you can run in developer tools and jsPerf test cases can be found at:
 * (message channel, slow) http://jsperf.com/setimmediate-with-message-channel
 * (no message channel, fast) http://jsperf.com/setimmediate-without-message-channel
