Get list of all generated chunks for 1.6.4 stuctures fix

Hi all!

I'm currently thinking about writing a plugins that will sequentially load, save and unload all chunk of all registered world in order to let the server write down the structures location to the world file (MC-15547). In other words, I would like to develop a plugin that will scan all my worlds to ensure that they will be compatible with upcoming release.

Now, I'm searching a way that I could get a list of all current generated chunks of each world. But, I cannot find such methods in the Bukkit API. Do anybody knows a way to accomplish that ? Or maybe doing something else that will help achieve my main goal ?

Thanks in advance guys for your help.
