This post prompted me to try my pet long-standing bug, where you have Dock auto-hiding on, show it, mouse away, mouse back before the sliding animation is finished, and see what happens. Previously the animation would just finish and it wouldn't show again, but in Golden Gate it does. Praise be. I did respond to an Apple survey a little while back and mentioned this one so maybe it got through...
this keeps the animation (although speeds it up a bit - replace 0.15 with another number to change it) it just removes the delay before the animation starts
