Runs Google Chrome with memory objects
To enable window.gc() on Chrome browser console you just need to start Chrome like this:
> /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --js-flags="--expose-gc" --enable-memory-info
Those flags enable the following console API, very usefull to debug memory leaks:
> console.memory // print memory information
> window.gc() // force garbage collection
