SlickSpeed

speed/validity selectors test for frameworks.

Every framework runs in its own iFrame, thus no conflicts can happen. Tests are run selector by selector, with an interval to prevent the browser from freezing.

Tests are run in a neutral environment, no library or framework is included in the main javascript test, to avoid favoritism.

The WebKit version of this test includes a number of modifications. Specifically
