     The program below (I hope I didn't goof up there) doesn't return
   any error either:

*sigh* i needed to pay closer attention to your perl script.

   
      [ ... ]
      if(pipe(f) != 0)
      [ ... ]


note that in NetBSD, pipe() is really a frontend for socketpair(), so
the fd's you get back from pipe are really sockets.  this is why the
getpeername() is able to succeed.  (FWIW, the sockaddr_in.sin_addr
for these results is 0.)
