To stop legislation from being passed - there's a limit to how long Congress can debate over a Bill. Talking it to death is a good tactic if the majority of the Senate will support the bill, but there is enough opposition to launch a successful filibuster. The reason this never really happens in the House of Representatives is because the House has a speaker. The threat of a filibuster is a far more common tactic than the real thing.
