Okay, but what form do you want the API to take for fences?
because I've just ported all this to using sem_file as the backend, instead
of sync_file which seems to oppose the goal of using it for fences.
For fences do you want upfront creation, then passing created fences object
into command submission that attach the internal fence?
Or do you want command submission to have out fence handles that it creates,
so we don't have any explicit syncobj create for fences?
Do you want those fences to be shareable across processes using sync_file
I kinda feel like I'm going around in circles here and I'm going to just merge
