In fact: I don't. But nevertheless, there is no time for the fragment to time
out (as I said I pretty much flood the interface, there are no duplicates and
I receive either all packets (with a very big MEM_SIZE) or non at all (with a
normal MEM_SIZE)). As far as I can see: completed datagrams are removed from
the reassembly buffer when the last fragment is received so there shouldn't be
any packets left in the reassembly buffer.
