I couldn't find any gem_wait() function or any other wrapper for the 
i915_gem_wait ioctl in ioctl_wrappers.c (except for gem_sync). There is 
a gem_bo_wait_timeout wrapper in gem_wait.c that could probably be moved 
to ioctl_wrappers, or I could just add the ioctl call here. What option 
would work better for you?

Thanks,
Daniele
