That's because I don't understand the issue you are pointing out. Are
you confused by the test of surface->p_lock in Release, whereas in Get
it's using sys->b_thread_safe ? I could use the same code. But one
cannot be set without the other. They are all using the same lock.
In Get you cannot use the lock from surface, since you're looking for
surface. In Release you cannot use the lock from sys because you don't
have access to it.
