The downside of using semaphores is that we lose metadata passing along the signaling chain. This is particularly nasty when we need to pass along a fatal error such as EFAULT or EDEADLK. For fatal errors we want to scrub the request before it is executed, which means that we cannot preload the request onto HW and have it wait upon a semaphore.
