Well, 'out' actually says to close the *other* direction, from external
process to Erlang - 'in' is more like what the OP is after. But both of
them take effect from the outset, i.e. a *uni*-directional channel is
created. What is asked for is a way to achieve the same effect later on,
specifically after having written some data in the ('out') direction
that is to be closed.
