I'm sure they can. And for some made-up benchmark it might even help.
Do people use it in real life?
The *big* wins come from being able to do compression/encryption
inline, when you don't need to do double-buffering etc.
Anything else is completely broken, imnsho. Once you need to
double-buffer your IO, you've already lost the whole point.
