So what primitives do you use? The lower-level descriptor-based 
primitives open() and friends? http://linux.die.net/man/2/open

What do you mean by direct buffer access?

What is the relative contributions of these (and possibly other) design 
decisions to the overall speed?

How can we integrate some of these in std.stdio without breaking 
backward compatibility, or offer additional artifacts that integrate 
seamlessly and don't need to be compatible?
