+"""PeaceKeeper benchmark suite.
+
+Peacekeeper measures browser's performance by testing its JavaScript
+functionality. JavaScript is a widely used programming language used in the
+creation of modern websites to provide features such as animation, navigation,
+forms and other common requirements. By measuring a browser's ability to handle
+commonly used JavaScript functions Peacekeeper can evaluate its performance.
+Peacekeeper scores are measured in operations per second or rendered frames per
+second depending on the test. Final Score is computed by calculating geometric
+mean of individual tests scores.

We have a new primitive now, tab.WaitForJavaScriptExpression(). Please use that

Nice find! I'm glad you figured out a way to split these up and automate them :)

Annie and I both looking into this and never figured it out.
