It seems that I found the cause.
I downloaded and installed vanilla Linux kernel 2.4.20 and
everything went fine. Then I installed variable HZ patch from
http://www.kernel.org/pub/linux/kernel/people/rml/variable-HZ/v2.4/
and set HZ to 1000. Shaping started to act not as I wanted.
Setting HZ back to 100 fixed the problem.
Is this some bug in HTB or HZ has to be set to 100?
