World::getBlockAt () at unloaded chunk

Hey,

I'm currently away from my dev machine, otherwise I would have done some testing before asking..
So:
What happens if you call getBlockAt() for a coordinate that lies in an unloaded chunk. Will it return null, some garbage, or will it load the chunk and return the block? (Or something else I can't think of)
If it will load the chunk: When will it be unloaded again? Right after the call? After a fixed period of time? Or just just when the server needs the memory to store some other chunks?

And also (this can probably only be answered by a dev): Is the current behaviour currently intended to be the "final one", or are there plans to make it act differently?

Fairly sure it will still return the correct block.
