It was a very long time ago. RFC 1122, in 1989, already said that the
TTL field is more a hop count than a real TTL.
Future RFC 6864 speaks about MDL (Maximum Datagram Lifetime) and,
relying on things like the reassembly timeout (RFC 1122, section
3.3.2), estimates it to two minutes.

To the *same* destination? (The ID only has to be unique per each tuple
{src, dst, protocol}.) It looks a lot.

That's an answer to my question: move all the traffic to IPv6 and the
problem will disappear.
