Verifying Lazy Loading behavior of code

A lot of times I write code that is supposed to do lazy loading. However it is tough to actually verify if in fact the lazy loading is taking place or did my code just load the entire set of data instead. With traditional debugging tools it would take a bunch of println() statements, a new build, and probably the entire lunch hour to verify the lazy loading behavior.

Note that in this case I am not 'debugging' in the traditional sense. I just want to verify whether my code is behaving at runtime how I want it to.

With Chronon, its instant. Just run your code and look at how it behaved in the time travelling debugger. No println() statements, new builds or anything special required.

We have made a video demonstrating this for a sample tree viewer with a lazy content provider.
