yes, I know.

the problem is that the module 'internet-node' is not supposed to depend
on the 'point-to-point' module. Furthermore, for the sake of writing
tests, I would like to test only what I am interested in, not some other
random piece of code like PointToPointNetDevice. i.e., I would like to
isolate the different components of the system to avoid testing
unrelated pieces when I really want to test UdpSocket.
