@aholmberg I'm not sure if I follow...it seems to me that if a
`RemoteConnection` implementation returns a list (or future list ) of
`FutureTraversers`, the traversal API can still remain independent from the
transport. Even if the GLV needs to operate on the Traversers,
`asyncio.Future`, `concurrent.Future`, and `tornado.concurrent.Future` have
compatible APIs (`done`, `cancel`, `add_done_callback`, `result`, `set_result`,
`etc.`). The "specialized" handling of the future, whether it be a coroutine
that requires a `yield`, `yield from`, or `await` expression, or a
`concurrent.Future`, will in the end be handled by application code written by
the end user.
