Well, I was thinking maybe you could return an appropriate error from loadResourceSynchronously that would get translated to StackOverflowError...

However... I notice now that loadResourceSynchronously asserts !loadingSynchronousRequest, which means that the previous WebCoreSynchronousLoader has to have already been destroyed at that point... so we shouldn't run out of fds, unless we're leaking GMainContexts or something?
