fast/ruby/ruby-svg-crash.html is flaky, when failing there is an additional line with right bracket in the output:

Same on Mac.

This failure means that notifyDone() is called before the main test function executes.

I'm not sure what exactly happens here. There are two possible mechanisms for the failure:

1. DOMContentLoaded fires substantially later than the inline script is executed. If parsing pauses right after </script>, that's quite possible.

2. Two chained zero-delay timers take longer than a 10 ms timer. I don't know if that's possible in WebCore.
