GVT forces single port submission of individual requests. We do not enjoy the context amalgamation that the test depends upon for setting up the test (where port 0 has a large number of requests with a priority change somewhere in the middle). Under single request submission of gvt it is quite able for the preemption event to occur while another context is active and so there be a real need to act upon that preemption.
