3864 * This help avoiding the "blocked-client" issues. The client is blocked if another client is doing begin-end stuff.
3865 * For now we eliminated polling that could occur on block, which caused a higher-priority thread (in guest) polling for the blocked command complition
3866 * to block the lower-priority thread trying to complete the blocking command.
3867 * And removed extra memcpy done on blocked command arrival.
3868 *
3869 * In the future we will extend CrHgsmi functionality to maintain texture data directly in CrHgsmi allocation to avoid extra memcpy-ing with PBO,
3870 * implement command completion and stuff necessary for GPU scheduling to work properly for WDDM Windows guests, etc.
