  # Hack to convert a string that represents a value greater than
2^31 -1
  # Look away!
  if (strlen(pieces[1]) > 9) {
  	bottom = int( substr(pieces[1],5) );
	top = int( substr(pieces[1],0,4) );
	pieces[1] = top * 10**5 + bottom; 
  }

That's my hack for now.  So, any number > 999999999 will be
converted.  This unnecessarily converts strings representing
numbers < 2^31 - 1, but whatever :)  It's straight-forward and
seems to work in my testing :D
