------- Additional Comments from Dmitry Titov <dimich at chromium.org>
I hope this is better. I've added
ScriptExecutionContext::isJSExecutionTerminated(), which is always 'false' for
Document and becomes 'true' for WorkerContext once Worker.terminate() or
WorkerGlobalScope.clsoe() is invoked.

Apparently, JSC does not crash on reentry while execution is terminated, it
will just cause another exception and almost immediate exit from the JS
fragment.
