Yes, I've looked at this stuff.

A goal of the new IO stuff is improved performance - or at least
support for high performance, which is not necessarily the same thing!

My thinking is that we should wait until 1.4 is actually released
before trying to implement any of the new APIs, but at that point
re-design our converter framework for maximum performance
compactible with the 1.4 APIs.
