Oops. I should've RTFA. They considered vmsplice() and thought it too much trouble to keep the processes' synchronized so messages don't end up buffered in the kernel. I don't see it. Either way signaling needs to occur between sender and receiver. I suppose all of this really cries out for a proper kernel AIO implementation (assuming there isn't one). Sender or receiver need a way to queue an op with an associated buffer.
