Okay, I'd suggest use default_xxx as prefix instead of simple_store_xxx,
because 1) more concise 2) won't cause confusion when people read the
farm code.

I'll go to update the farm's io path to use defaul_xxx functions, I
think this simple store implementation can be nicely applied to farm.

Thanks,
Yuan
