Hey, I just found a bind bug ticket in my queue about bind.  I noted
that on stable/6 stable/7 stable/9 & head the referenced code "fails".

It seems that this is a problem, but I have no idea if its a real
problem or not.  Our devs think it is.  Anyway, here is a code snippet
to show the failure in bind.  On linux/solaris this does not fail.

http://people.freebsd.org/~sbruno/bind_test.c

simple compile with gcc -o test test.c and run as normal user.
