That "someone" could be a bad guy playing dirty games with your box and
certainly knowing what he's doing.  :-)

So far, noone gave me a real example where using of net 127 outside
loopback would be useful.  If there such an example exists, we should
wrap all three checks into a sysctl, including ip_input(), ip_output(),
and in_canforward() parts, where ip_input() exists for almost a year,
and in_canforward() existed since 1987.
