That is actually quite awkward. Smooth interlocking of coroutines
suggests you should be able to introduce a blocking state anywhere with
a "yield from" statement. To avoid the problem you mention, you'd then
have to give up direct function call altogether and yield from
everything under the sun:

     # Use the supercomputer over RPC -- or not!
     root = yield from my_math.sqrt(x)

It could be done, but it won't look like Python code anymore. It
probably won't look like a computer program anymore.
