However, sometime the opposite is true and you have to wait for the batch you want to start before pulling the trigger. I'd put a usleep(100) in there /* Wait for batch to execute */ and we should put the wait-for-execution ability in igt_spin_t. Unfortunately that requires MI_STORE_DWORD_IMM (or more creativity) limiting it's availability.
