Help with coroutine-based state machines?

Almost everything.

Generators serve at least three purposes for state machines:

(1) They avoid function call overhead (much faster)
(2) They let you branch into the middle of an execution context (where
    you left off).
(3) They let you (easily) save local values for when you return to a
    state.

Your approach loses all of those benefits (and doesn't even get rid of
the 'while' loop, just imposes a narrow condition rather than more
flexible breaks from a 'while 1').

Yours, Lulu...
