Previously, we didn't report a failure to reset the state to consistent values, and just silently relaunched the process. Quite surprising that this happens on this particular test.

I have not been able to report this timeout locally. Marked test as a timeout on mac release in r201306

Marked as flaky on ios-simulator-wk2 release in <https://trac.webkit.org/r201344> I am still working to reproduce this timeout locally.

I can hit this on a debug build when running tests like this: run-webkit-tests mathml/very-large-stretchy-operators.html mathml/wbr-in-mroot-crash.html --iter 100 --debug-rwt-logging

Unsurprisingly, WebContent process is busy painting the previous test.
