Sure, but that would preclude using overlapped IO in the standard Handle 
implementation, which is where we need it right now.  You want to be able 
to do ByteString IO using overlapped IO underneath, for example.

I'm not claiming this is a good long-term plan, but in order for it to be 
useful *now*, it has to go into base.
