I'll be glad to use pfifo_fast but adding that qdisc explicitly I get a
segmentation fault. If I don't add a leaf qdisc, how can I be sure
pfifo_fast is used? Or it's just a pfifo?

_In proportion of its allocated share._

I am certain that CS does not have large banwidth requierments, but it
needs very low latency. If I was to allocate a real bandwidth quantum,
then the competition between CS and other traffic (MAN and Internet)
would not be fair even if it has the lowest prio. So I had to lie htb
about the available bandwidth based upon the fact that bandwidth
requirements for CS are low and bursty. HTB would not allocate bandwidth
to a service that doesn't need it. (Or so I think; I may be wrong about
that... Please correct me if I do.).

I need more that one root class, because the bandwidths are separate and
not supperposable. So what MAN can spare, Internet cannot use and
vice-versa. (And MAN can spare a lot!)
I tested a setup with a 1:A root class and 1:1; 1:2; 1:3 and 1:4 were
child classes of 1:A. I got the same results. But I needed to lower the
latency so I deleted that 1:A root class...
