Well, for a lot of devices, you'd need a barrier after every single
operation.  That can become tedious to type, and could be more overhead
in terms of function calling, if the barrier can be in-lined.

What I'm saying is "redefine part of the interface" to match what is
basically current practice, and provide a hook to enable the the more
efficient mechanism for devices which can reasonably take advantage of it.
