Note that teh IO _completion_ can happen in user land. That does not mean
that the IO page tear-down can (or should) happen at the same time.

There are two issues here:
- the data structures supporting the IO, built up and torn down from
process space.
- the IO itself.

One is synchronous, the other is not.
