I think this is pretty smart, actually.  Deferreds, futures, promises,
etc. give the programmer a lot of rope.  They don't require classical
models of control flow, in particular.  That's cool, but tends to lead
to code with subtle bugs.

Coroutines re-introduce just enough structure to put programmers back
in comfortable territory for verifying correctness.  This ends up
looking a bit like threads, but with less concern for synchronization
primitives, and virtually-free cloning.
