Here you go. It's called "cloture" and has been around since 1917. As I said before, the way to head off or stop a filibuster (which is now procedural, not spoken) is to threaten the filibustering party with dire consequences that a simple majority can inflict on them. At least, that's what a majority party with any cojones will do. If the majority leadership is weak, as it was under Lott, they will offer inducements instead.
Thank you! That is a fantastic link.
