Jut nitpick,
Original code also uses the 'unsigned nid' but now it assigned
'unsigned nid' to 'int nd' at here. does it right? 

node id is generally signed, we use -1 as a special value indicating no
node preference in a number of places. Not sure why it was unsigned
here. Also I think even SGI isn't anywhere near 2^31 nodes.
