I'm almost sure (but have no references to back my claim) that ttl is
considered a hop count now, so it won't be decremented by more than 1
even when a packet is queued several seconds.
>From RFC1812, 5.3.1:
When a router forwards a packet, it MUST reduce the TTL by at least
one. If it holds a packet for more than one second, it MAY decrement
the TTL by one for each second.
I believe most implementations reduce the TTL by only one (a quick check
to linux source says it goes that way)
