@gruehle once warned me about adding things to the stat object deviates from the w3 spec but I can't seem to find a w3 spec.  @gruehle do you know where this is?  Node adds quite a bit of data to their stat object and I'd like to also add the fullpath because callbacks needing to know the path of where a stat callback is coming from need to create a function with the path inside a closure to get to this data and it would be nice to not have to do that.
