The constants are used in different objects, so I'm not sure there is a sensible way to to do this. A constant reference to a private object might be a way, but that felt like too much indirection.

Changed to 2s interval between subsequent polls since there have been a few concerns about this :-). I also agree that a native implementation would be far superior.
