Bus holders aren't intended as dynamic clamps. They generally have high-kohm
impedances -- hardly adequate for damping. Their purpose is to keep the bus
in a defined logic state so that inputs don't exhibit high crowbar currents
during bus float.
BTW, *please* don't post the animated graphics. They pretty near locked
up my 56k dialup line at home.
