Originally reported on Google Code with ID 7042

When open multiple safari with the following code in .Net, I can see only 1 safari window
successfully executed the navigation function. Actually it opens multiple safari window,
but all other window hang there. 
The following code works well with Chrome Driver. 

            Parallel.For(0, 5, i =>
            {
                SafariOptions options = new SafariOptions();
                options.SkipExtensionInstallation = true;
                IWebDriver driver = new SafariDriver(options);
                //IWebDriver driver = new ChromeDriver();
                driver.Navigate().GoToUrl("http://google.com");
                driver.Dispose();
            });

Error returns as follows:
Unhandled Exception: System.AggregateException: One or more errors occurred. ---> OpenQA.Selenium.WebDriverException:
Di
d not receive a connection from the Safari extension. Please verify that it is properly
installed and is the proper vers
ion.

The Safari driver explicitly only supports one instance at a time. It's a current limitation
of the driver.
