Multi-Column Layouts Climb Out of the Box

A project I recently worked on required an elastic layout with two columns of equal height, each with a different background color. As usual, there was no way to tell which column would be taller. I immediately thought of Dan Cederholm's Faux Columns, but I needed an elastic layout. I also looked at the One True Layout, but this seemed buggy and required too much extra markup and too many hacks for my taste.
