Regarding (2) below, it looks like if there is only one node,
nam does not display properly.  I guess that's okay.  For
this case, the grader will look at your output file and
make sure the right informatin is in it.

  You need to do a flush() to make sure.

  Hmm... I don't remember if this is suppose to work.  I'll
  try it when I get to a Linux machine.

  Since TTL is 1 for NOTIFY messages, it doesn't matter because
  its neighbor will not forward the message!  Right?!
