A regression in 4b0cdf9123 caused the
basic send/recv functionality to break for simple scenarios. This was
due to inadequate testing, and a partial misunderstanding of the
situation.
New testing should hopefully catch more cases, but send/recv and
compile-time checks are still not as complete as is probably possible.
