findroute simply asks the node to do a lookup.

findroute should give you the path length.  and from that, if you
have the pairwise latency matrix, you can calculate the stretch.

It's a little complicated and depends on which lookup
method you are using.  You could start by looking in
route_chord.C.  Ignore anything you see about upcalls
which are currently not used.
