Comment (by tibbe):

 I generally agree with thoughtpolice's comments. At this point I don't
 think we will get much further without building a prototype or two.

 I think moving the I/O manager into the scheduler can also remove some
 complexity:

  * We now have a bunch of Haskell-side global state that could live more
 naturally on the capability data structure.
  * The synchronization situation would be a bit simpler inside the RTS
 (and there would be one less thread).
