Likewise, the BRL gateways will discard incoming datagrams with
packet counts of zero or one.  Hence, any datagram that comes in
with a TTL of Zero will be discarded and datagrams to be forwarded
that have a time to live of zero after they've been decremented are
discarded as well.

The SPEC says that the packet will be discarded when the time to live
is detected as being zero.  We interpret that to mean at any time
prior to transmission.
