I just don't have any use case for it, so we would be writing code to
write tests for it.

That doesn't seem smart.

If there is a future non-testing use case, the API is expressive
enough for someone
to add a flag or new sync obj to allow polling and to add support in a
nice easily
digestible patch.

Dave.
