This page's JavaScript calls console.profile() but not console.profileEnd().
To use this test, load it in the browser then load the WebInspector and look at
the profile. You should see the profile running (when that feature is implemented 6060556).
Then navigate to another page and check the WebInspector again. Safari should not
have crashed and the Inspector should not show a profile (unless we allow cross-load
profiling in the future 5951478 5954912).
