The kernel is now enforcing that clients are not allowed to block higher priority contexts from accessing the GPU; one is no longer allowed to sleep for a second hogging the GPU. Reduce the sleep down to 50ms, short enough not to anger the preempt-off checks while long enough for any ordinary GPU work to complete.
