nsAccessible implementation of nsIAccessibleSelectable clearSelection and selectAllSelection aren't performant because for every found selectable child they call SetSelected which ensures again if this child can be selected. We need to get rid this double search (from parent to child, from child to parent). Also it sounds we could improve SetSelected(PR_FALSE) if we won't check whether the accessible is selectable or not, it's not awful if we just remove ARIA aria-selected attribute if any.
