Five years ago I removed a once per packet microuptime call which led
to something like a 33% improvement in throughput.  I don't want to
have to do that again. :)

Hey I just realized that hfsc calls microuptime() for every single packet at dequeue time.

altq_hfsc_dequeue() --> read_machclk() --> microuptime()

Looks like codel won't be slowing hfsc down at least. :)
