Nice idea making your synchronous code work like this too.

Have you considered using the @inlineCallbacks decorator instead?  I bet
you could make that work too, you could write your own decorator that
uses inlineCallbacks or something synchronous, then the above becomes:

def get_foo(arg1, arg2):
    args = prepare_request()
    result = yield make_maybe_blocking_call()
    finalValue = do_more_stuff(result)

Which can be a lot neater when you get stacks and stacks of callbacks.
Python's lack of a block construct otherwise makes that really unpleasant.
