Prime95 (or MPrime for Linux) with huge data sets. Run one instance per CPU, and make sure that the data set size is going to cause plenty of swapping.

This also has the advantage that it'll exercise your RAM pretty well. If I've got some suspect RAM, I run it (without the swapping) for a couple of hours, then I run memtest86 once the chips have warmed up a bit.
