Sending channels over channels
------------------------------

Some advanced usage of subinterpreters could take advantage of the
ability to send channels over channels, in addiction to bytes and None.
Given that channels will already be multi-interpreter safe, supporting
then in ``RecvChannel.recv()`` wouldn't be a big change. However, this
can wait until the basic functionality has been ironed out.
