    netchan: use acknowledgements on export send. · d54b921c

    Also add exporter.Drain() to wait for completion.
    This makes it possible for an Exporter to fire off a message
    and wait (by calling Drain) for the message to be received,
    even if a client has yet to call to retrieve it.
    
    Once this design is settled, I'll do the same for import send.
    
    Testing strategies welcome.  I have some working stand-alone
    tests.
