This test is really slow on some Windows systems. The following is an example from Windows Server 2013 with lots of resources. The test took close to 18 minutes to pass (I had to run with -timeoutFactor set very high to avoid timeouts). The reason for the slowness is not clear, maybe the test needs more output to help diagnose issues like this.
