Performance could be a bottle neck in some situations. I'm particularly
worried about what the performance implications will be on the Loader
spec with it's heavy use of promises. With that spec there will be a
minimum of (I think?) 5 Promises created for every module, and perhaps
many more if custom loaders are used. When you do the math that's going
to wind up being a lot of Promises, which always have to go on a task
queue, to a load non-trivial sized applications and the performance
might be much worse than a non-async continuation passing API.

I'd like to see this data before I conclude Promises solve all of our
continuation needs.
