Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter). This is mostly focused on SBCL performance, though it is entirely portable, and other implementations should benefit as well. Implementation-specific contributions welcome.

The primary interface is not stream-oriented, but a stream interface is also provided.
