of course the latency increase depends on how full are the buffers,
and the worst case is easier to determine by back-of-the-envelope
calculations:
queue_slots * max_pkt_size / bottleneck_link_speed
e.g. if you have 100 slots and an MSS of 1500 and a 10Mbit
bottleneck you are adding (100*1500*8 / 10000000) = 120ms latency.
