ignore_sticky_posts in WordPress 3.0.3?

ignore_sticky_posts was introduced in WordPress 3.1. Before this version, you can use caller_get_posts, which will have the same effect (this option was used when you queried the posts via get_posts(), which uses the same WP_Query class in the background, but should ignore sticky posts). The name was a bit confusing, and thus changed in 3.1.
